Recently, a new wireless technology, i.e., Worldwide interoperability for Microwave Access (WiMAX), has been demonstrated to have its strong potential to provide a very high speed of broadband services. By simultaneously using multiple antennas at transmitter and receiver sites, these systems exploit the spatial dimension of the propagation channel. The development of such antennas includes the design of array antenna, optimizing the array antenna parameters and thereby increasing its performance. This paper mainly focuses on design of single microstrip patch antennae and linear array configurations by optimizing the various antenna parameters such as directivity, gain, Mutual coupling and beamwidth etc., Microstrip array antennae designed and simulated using IE3D for WiMAX application operating at 2.4GHz and the same configurations are also optimized and analyzed. In this analysis, upon comparing the parameters such as gain, directivity, return loss and 3-dB beamwidth quantitatively it is proposed that the linear array promises very narrow beamwidth with optimized gain.

This paper explore about the micro strip patch antenna design with a defected ground structure (DGS) for dual band operation. The intend of this paper is to design an micro strip antenna, under the frequency at 2.4 GHz and 5.2 GHz that can be utilized for BLUETOOTH and WLAN applications. The feeding technique used here is coaxial feed technique. The above said double band property can be established by etching U-slot in the ground plane. Being periodic structure slot is selected and it is imposed on ground plane. The periodic structures naturally modify the method of propagation of the electromagnetic signal passing on to the antenna. Essentially its core is to vary the parasitic capacitance and inductance of the material through which the substrate is made. This may moreover leads to the reduction in size and progress the performance of the antenna. Micro strip patch antennae are favored due to the fact that these are small in size, inexpensive, consume low power and easy to fabricate and also be designed to meet wide band application requirements.

As wearable electronics become more prevalent in everyday life, there is a growing desire to integrate circuits and antennae into clothing. One way that this integration may occur is through use of electronic textiles (e-textiles). However, changes in environmental and wear conditions may affect the conductive data communication performance of the e-textile, such as surface resistivity and antenna radiation characteristics. In this study, the effects of pilling, wrinkling, abrasion, and laundering of e-textiles were examined for resistivity performance. E-textile resistivity performance from both direct current (DC) and radiofrequency (RF) perspectives were measured following AATCC and ASTM standards. For DC performance, results indicate that pilling causes severe damage to e-textile resistivity, while laundering and wrinkling did not substantially affect e-textile resistivity performance. For RF performance in this study, an e-textile microstrip patch antenna was designed and data were collected under similar environmental and wear conditions. RF performance change corresponds with DC performance change. The findings of this paper highlight limitations of the evaluated e-textile performance, and provide new perspectives regarding improvements to e-textile fabrication for sustaining performance through environmental and wear operations.

Wearable technology has recently attracted much interest for various uses. An essential component of the wearable system is the wearable antenna. Textile and non-textile materials have both been used to create wearable antennas. Textile antennas are very useful and widely used nowadays, particularly in body-worn applications monitoring health parameters. Fabricated using microstrip technology, textile antennas have various benefits, including small size, lightweight, simple fabrication, and ease of wear. In this study, a microstrip antenna is created utilizing a substrate made of jeans. It works between 2.4 to 2.5 GHz in the ISM (industrial, scientific, and medical) band. High-frequency structure simulator (HFSS) software was used to simulate two antennas, one with an incomplete and the other with a complete ground plane. Wearable antennas can protect the body from the impacts of RF radiation by utilizing the entire ground plane principle. Results from a vector network analyzer were obtained for the fabricated antenna (VNA). This antenna's main function is to track blood glucose levels. Blood's dielectric characteristics change when blood sugar levels fluctuate, affecting the antenna’s output frequency. There are two ways to monitor glucose levels. One method requires placing a finger on an antenna patch, while the other involves fixing an antenna to a person's arm and detecting the output frequency fluctuation. The antenna's resonant frequency raises in reaction to increased blood glucose levels. Therefore, these textile antennas are a great choice for non-blood sample monitoring of blood glucose levels.

The design of the antenna for a 5G environment has advanced quickly in the field of wireless communication in this world. This paper focuses on the layout and analysis of a square microstrip patch antenna (RMPA) for 5G. Low prices, ease of fabrication and low profile are just a few of the benefits of microstrip antennas. The microstrip patch antenna's inherently low impedance bandwidth is a chief disadvantage. Microstrip antennas can be made smaller or smaller by way of placing a particular slot into the radiating patch. In the final couple of decades development in wireless communique has grown, and so using wi-fi communication is growing in fantastic amount. Microstrip Patch Antenna is certainly of the sort a radio antenna can be set up on a low profile. The reduced antenna length for such an antenna corresponds to the meandering of the excited patch floor current paths because of loading the slots inside the radiating patch. This can decrease the fundamental resonant frequency of the antenna. This antenna covers three regions, substrate made-up of FR4 epoxy, patch and ground made of copper fabric. This antenna affords an awesome return loss of -13.07 dB, VSWR as 1.

Modern communication system is based on wideband communication. A wideband antenna is designed in such a way that it will receive a wide range of frequencies. Microwave frequency spectrum is classified as ranging from 1GHz to 100GHz and this range is divided into a number of frequency bands. These bands are defined as L Band, S Band, C Band, X Band etc. To fulfil the demands of many users patch antenna is designed in these bands. Among different types of antenna, Microstrip Patch Antenna is most popular in wireless communication system. Microstrip patch Antennas have many advantages over other familiar antennas because microstrip patch antennas are of low profile, low cost, low volume, light weight. Low efficiency, low gain and narrow bandwidth of patch antenna create major challenge to a designer. Slots are created on patch for preparing antenna forwideband applications.

The paper proposes a simple four-element microstrip patch array antenna fed with corporate-series technique. The paper compares the proposed design with four-element antennas fed with only series-fed and corporate-fed microstrip antennas. All three antenna designs use rectangular microstrip patch elements with two insets and slots on both sides of the patch. The patch elements are accompanied by Yagi elements: three director elements and two reflector elements. Through comparison of simulation results, the paper shows that four-element array antenna with combined corporate-series feeding technique performs better compared to antennas with only either series or corporate feeding network. The proposed corporate-series fed antenna achieves better performance with wide frequency bandwidth of 25.04–30.87 GHz and gain of 9.5 dB. The antenna has an end-fire radiation pattern. Overall performance shows that the proposed corporate-series-fed microstrip patch antenna with Yagi elements is suitable for next generation 5G communication.

Abstract. The antenna cross polarization suppression (CPS) is of significant importance for the accurate calculation of polarimetric weather radar moments. State-of-the-art reflector antennas fulfill these requirements, but phased array antennas are changing their CPS during the main beam shift, off-broadside direction. Since the cross polarization (x-pol) of the array pattern is affected by the x-pol element factor, the single antenna element should be designed for maximum CPS, not only at broadside, but also for the complete angular electronic scan (e-scan) range of the phased array antenna main beam positions. Different methods for reducing the x-pol radiation from microstrip patch antenna elements, available from literature sources, are discussed and summarized. The potential x-pol sources from probe fed microstrip patch antennas are investigated. Due to the lack of literature references, circular and square shaped X-Band radiators are compared in their x-pol performance and the microstrip patch antenna size variation was analyzed for improved x-pol pattern. Furthermore, the most promising technique for the reduction of x-pol radiation, namely "differential feeding with two RF signals 180° out of phase", is compared to single fed patch antennas and thoroughly investigated for phased array applications with simulation results from CST MICROWAVE STUDIO (CST MWS). A new explanation for the excellent port isolation of dual linear polarized and differential fed patch antennas is given graphically. The antenna radiation pattern from single fed and differential fed microstrip patch antennas are analyzed and the shapes of the x-pol patterns are discussed with the well-known cavity model. Moreover, two new visual based electromagnetic approaches for the explanation of the x-pol generation will be given: the field line approach and the surface current distribution approach provide new insight in understanding the generation of x-pol component in microstrip patch antenna radiation patterns.

Microstrip patch antennas that are multiband and downsized are required to suit the high demand of modern wireless applications. To meet this need, a one-of-a-kind triple band array antenna has been proposed. The proposed 2x2 microstrip patch array, which comprises of four hexagon-shaped radiating patches are electromagnetically excited by a centrally positioned microstrip feed line in the same plane along with a slotted ground plane, is investigated. CST Microwave Studio, a powerful 3D electromagnetic analysis programme, was used to design and optimize the array antennas. The 2x2 array antenna was constructed on a FR-4 substrate with a dielectric constant of 4.3, a loss tangent of 0.001, and a height of 1.6mm. To optimize energy coupling from the feed line to the radiating patches, the ground plane has an H-shaped groove cut into it. The suggested 2x2 array antenna's multi- frequency behaviour is shown. Three resonant peaks were detected at 1.891GHz, 2.755GHz, and 3.052GHz. The observed bandwidths for these resonances are 234MHz, 69MHz, and 75MHz, respectively, with measured gains of 7.57dBi, 6.73dBi, and 5.76dBi. The goal of this work is to design, build, and test a single layer proximity fed array antenna. Standard proximity fed array antennas contain two substrate layers; however this array antenna has only one. As a consequence, the impedance matching and alignment are better. Simulated and experimental results showed that the this 2x2 array antenna operates in various important commercial bands, such as L and S bands and the array antenna might be beneficial for a wide range of wireless applications. The proposed antenna has good Impedance, S11, and radiation qualities at resonant frequencies. In this work, the 2x2 array antenna with hexagon-shaped radiating patches was successfully created utilizing the single layer proximity fed antenna concept and gap coupled parasitic patches.

A stacked multi-layer substrate integrated waveguide (SIW) microstrip patch antenna with broadband operating bandwidth and low cross-polarization radiation is provided. A complete study on the propagating element bandwidth and cross polarization level is presented to demonstrate the importance of the design. The proposed antenna includes three stacked printed circuit board (PCB) layers, including one layer for the radiating 2 × 2 rectangular patch elements and two SIW PCB layers for the feeding network. There are two common methods for excitation in cavity-backed patch antennas: probe feeding (PF) and aperture coupling (AC). PF can be used to increase the bandwidth of the antenna. Although this method increases the antenna’s bandwidth, it produces a strong cross-polarized field. The AC method can be used to suppress cross-polarized fields in microstrip patch antennas. As microstrip patch antennas are inherently narrowband, the AC method has little effect on their bandwidth. This paper proposes an antenna that is simultaneously fed by AC and PF. As a result of this innovation, the operating bandwidth of the antenna has increased, and cross-polarization has been reduced. Actually, the combination of probe feeding and aperture coupling schemes leads to achieving a broadband operating bandwidth. The arrangement of radiator elements and cavities implements a mirrored excitation technique while maintaining a low cross-polarization level. In both numerical and experimental solutions, a less than −30 dB cross-polarization level has been achieved for all of the main directions. A fractional impedance bandwidth of 29.8% (10.55–14.25 GHz) for S11 < −10-dB is measured for the proposed array. Simulated and measured results illustrate good agreement. Having features like low cost, light weight, compactness, broadband, integration capabilities, and low cross-polarization level makes the designed antenna suitable for remote-sensing and satellite applications.

Microstrip patch antenna is a compact antenna which suffers the limitations of poor gain and reduction in radiation pattern. To reduce the resonance frequency of microstrip antenna increases the length of surface current with help of cutting slots in the patch. In this paper, a comparison of four Microstrip antennas with unequal length of rectangular slots is proposed. The microstrip antennas having rectangular shaped ground plane and FR4-epoxy substrate with relative permittivity 4.4, relative permeability 1 and dielectric loss tangent 0.02 with an overall size of 100×100×5 mm3. The performance of antennas is compared with slots in the patch and the effects of rectangular slots using operating frequency of 8 to 12 GHz are presented.

In recent years monetary narrowing impact more on Turkey and developing countries. Therefore, the importance of industrial policy and technology management in developing countries has widely increased. Production and design strategies have to be planned carefully. Thus, evidently monetary narrowing and undesired exchange rate fluctuation affected investment and the cash flow in numerous sectors such as finances, funding, industry, service industry, agribusiness, livestock, building trade, research, and development, etc. In this context, this situation broadly hit the research, prototyping, manufacturing, and testing phase of the microstrip patch antennas. Today, patch antennas have widely utilized in telecommunication systems. Hence, this growth has increased interest in studies. As it is in every project, cost and efficiency are an essential part of the project design. Therefore, the ratio of cost is more important for Turkey and developing countries due to undesired exchange rate fluctuation, tax, financial obligations, and unexpected world events (e.g. COVID-19 pandemic). Commonly, the microstrip patch antenna comprises particular parts such as a radiating patch on top of the double-sided laminate and ground plane and feeding point located below the double-sided laminate. Therefore, microstrip patch antenna components play a significant role in patch antenna radiation characteristics. Moreover, specifications of the double-sided laminate, such as relative permittivity (or dielectric constant) and real physical thickness are essential elements of the patch antenna's radiation characteristics. Generally, high-quality dielectric substrates are developed and manufactured by western originated companies. Thus, the dielectric substrate with high-grade characteristics is hard to find for Turkey and developing countries. Importing is the only option and quite costly. Choosing a domestic dielectric substrate is inevitable, however insufficient for many cases. In this study, difficulties in microstrip patch antenna production and prototyping in Turkey are analyzed.

Abstract-Local Area networks work in frequency ranges 900 MHz, 3.6 GHz, 4.9GHz, 5 GHz, 5.9 GHz, 6 GHz and 60 GHz. It supports broadband communication and provides end to end communication without any propagation delays. For establishing LAN network, antennas are employed to transmit and receive signals. But the existing antenna designs for wireless LAN cannot accommodate higher bandwidths even though they provide good gain. Microstrip patch antennas are considered as they have high compatibility rates, low volume and are easy to manufacture. This paper proposes the design of a microstrip patch antenna with effective bandwidths at 1 GHz and 2.4 GHz using microstrip feed technique with dielectric materials such as FR 4 Epoxy, Arlon 450 and Taconic35. The results are shown in graphical format and have been tabulated. From the results we can conclude that FR 4 Epoxy with 1.6 mm substrate height has given best results among Taconic 35, Arlon 450 and FR 4 Epoxy. From the results we can conclude that we have achieved better bandwidths when compared to the previous works available.

In this article, the feasibility of using a circular microstrip patch antenna to measure strain and the effects of different materials on sensitivity of the patch antenna are investigated. Also, the effect of strain direction on the frequency shift is studied. The theoretical model shows a linear relationship between strain and the shift in the resonant frequency of the antenna in any material. Both finite element analysis (FEA) and experimental tests have been undertaken to corroborate the relationship between strain and frequency shift. In addition, a new antenna sensor based on a meandered microstrip patch antennas has been designed and tested to overcome the shortcomings of the circular patch. The meandered circular microstrip patch antenna exhibited a threefold increase in sensitivity and a fivefold reduction in its physical size, when compared to the simple circular patch. The ultimate intention of this work is to configure antennas for the detection of relatively small damage zones in structures and to do so wirelessly.

In smart textile systems, the wireless communication between the wearer and the wider environment plays an important role, especially in medical applications. This can be achieved by integrating an antenna in textile materials. The low-profile microstrip antenna is a desirable choice for textile antennas and integrating this type of antenna into the three-dimensional woven fabric achieves the most integrated textile antenna structure up to now. Different from traditional antenna structures, the three-dimensional woven fabric integrated microstrip antenna has the radiation patch and ground plane totally woven with the yarns, where the radiation properties would strongly depend on the weaving structures and parameters. In this paper, a 1.9 GHz single patch microstrip antenna was designed and six types of antennas with different combinations of woven patches and ground planes were compared. The measured results showed that the three-dimensional woven antenna had adequate performance. In addition, the three-dimensional woven antenna with warp yarns parallel to the feeding direction exhibited a better return loss and radiation pattern than the antenna with weft yarn parallel to the feeding direction, due to the longer current path for the latter antenna based on simulated current distribution analysis. Furthermore, the effects of conductive yarn parameters on the antenna properties were discussed and yarn structures were suggested to obtain relatively ideal antenna performances.

The small volume of microstrip antennas has low production costs and easy production, which has accelerated the work in this area. The disadvantages are narrow bandwidth and low gain. In wireless communication, antennas with low return loss and high bandwidth are required. The bandwidth and power gain of the microstrip patch antennas should be increased optimally. This article presents the design of the broadband microstrip patch antenna operating in the ISM 2.4 GHz band (2400-2485 MHz). The study includes three-dimensional antenna model, simulation phase and fabrication / measurement phase. For the low cost of the antenna, FR-4 with the relative dielectric constant 4.3 and the loss tangent tan 0.02 is preferred as the substrate material. Dielectric material thickness is determined as 1.6 mm. The length of the feed line and the dimensions of the rectangular patch were found by mathematical calculations with the transmission line model. There are slots on the antenna, which is a very simple method in order to improve the bandwidth, gain and directivity parameters of the antenna. In the article, four different designs are presented, the results are compared and the proposed antenna has 979 MHz bandwidth and 2.68 dBi directivity gain at -10 dB at the resonance frequency of 2.316 GHz. The changes made in the antenna design have improved the results such as gain and bandwidth compared to the conventional microstrip patch antenna. The proposed antenna is suitable for use in mobile communication.

Examining and evaluating the improved microstrip patch antenna to enhance the performance by the initial objectives are the main contribution of this paper. To achieve multiband operation, the patch's shape is first adjusted later microstrip patch with the slot presented. With the help of the Ansoft HFSS antenna simulator, functional analysis has been shown to examine the impact on antenna resonant frequency. A probe-driven microstrip patch antenna imprinted on FR4 epoxy substrate with 1.6mm thickness and a dielectric constant of 4.4 is developed in this work via the HFSS tool for wireless applications operating between 2 to 5GHz. To achieve multiband operation, the structure of the patch is varied. The impacts on antenna resonant frequency are examined through numerical simulations. The length, as well as the width of a traditional patch antenna, is initially computed, and further, an appropriate patch dimension of 28.3mm x 36.9mm has been determined. For multiband operation over the frequency ranging between 2 and 5GHz wireless applications, a probe-driven microstrip patch antenna imprinted on FR4 epoxy substrate with 1.6mm thickness and a dielectric constant of 4.4 is built via the HFSS tool. The proposed architecture of a traditional microstrip patch antenna is imprinted on an FR4 epoxy substrate with a 1.6mm thickness and a 4.4 dielectric constant. The proposed antenna design is illustrated for the 3D structure of the Mutual Coupling Steered Array-Lens Antenna System (MPA) with an improved patch. To achieve multiband operation, two slots are inserted on the edges of the patch, and both the slots are 2mm wide, as well as the depth of the slots is modified to see how it corresponds to the resonant frequency.

AbstractIn this paper, theoretical analysis of microstrip line fed rectangular patch antenna loaded with parasitic element and split-ring resonator is presented. The proposed antenna shows that the dualband operation depends on gap between parasitic element, split-ring resonator, length and width of microstrip line. It is found that antenna resonates at two distinct resonating modes i.e., 0.9 GHz and 1.8 GHz for lower and upper resonance frequencies respectively. The antenna shows dual frequency nature with frequency ratio 2.0. The characteristics of microstrip line fed rectangular patch antenna loaded with parasitic element and split-ring resonator antenna is compared with other prototype microstrip line fed antennas. Further, the theoretical results are compared with simulated and reported experimental results, they are in close agreement.

The development of cellular technology has now entered the 5th generation (5G), this 5th generation provides 3 types of services, eMBB (enhanced Mobile BroadBand), URLLC (Ultra-Reliable and Low-Latency Communications) and mMTC (massive Machine Type of Communications). One of the important devices in 5G technology is an antenna device which is able to support these 3 services. 5G technology requires an antenna that has high performance. There are various types of antennas, one of which is a microstrip antenna. Microstrip antenna is one of the most widely used antennas in telecommunications because of its light mass, small dimensions and easy fabrication. There are various ways or methods that can be done to overcome the narrow bandwidth of microstrip antennas, by increasing the thickness of the substrate, using parasitic elements, reducing the value of the dielectric constant, adding inserts to the feeder, or by modifying the patch by adding slots on the patch antenna. In this study to improve the performance value of the microstrip antenna, the researchers discussed increasing the reflection coefficient by adding X Slots to a microstrip antenna with a working frequency of 3.5 GHz for 5G communication. The results of this study showed an increase in the reflection coefficient of 67%, and an increase in bandwidth of 5%.

In this paper, the design and simulation of rectangular microstrip antenna arrays for improving antenna gain is performed for point-to-point application. The proposed design is composed of four elements microstrip antenna with an array configuration operating at 5.8 GHz. Each element is constructed from four truncated arrays radiating elements and an inclined slot on each patch which capable to achieve circular polarized capability. The design of the 2x1 and 2x2 of rectangular microstrip array antenna was implemented from the designed of single rectangular patch antenna as the basic building element. The designed 2x1 and 2x2 array were fed by microstrip transmission line which applied a technique of quarter wave impedance matching. The antenna design was etched on Rogers RT 5880 substrate with 2.1 and 1.53 mm of dielectric constant and thickness respectively. All the designed structure were simulated in CST software. The main results of the designed antennas were compared in terms of gain, axial ratio and return loss. Based on the return loss simulation results, the designed antennas resonated exactly at the desired resonant frequency of 5.8 GHz which indicates good antenna designs. Compared to the single patch antenna having an antenna gain of 8.26 dB, the 2x1 and 2x2 arrays achieved a gain of 10.24 dB and 13.29 dB respectively. The results show that the designed rectangular microstrip antenna arrays have an improved gain performance over the single patch antenna.

In this study, the design uses three variations for silver nanowires and three variations of patches. Variations of silver nanowires are in the form of length, diameter and number of silver nanowires, while for patches, variations of single patch, double patch and triple patch are used. The microstip antenna uses a patch specification with a thickness of 0.035 mm made of copper, with a density of 1.6 mm for a substrate made of FR-4 epoxy. Based on the observations of the antenna parameters from the characteristics of the silver nanowires variation, the desired results were obtained at variations in diameter of 300 nm, length of 32 mm and the number of 342 silver nanowires in triple patch with return loss = -20,731 dB; VSWR = 1.202; gain = 5,338 dB and directivity = 9,970 dBi. The above results have increased the desired value compared to triple patch microstrip antennas without nanowires with a return loss value = - 16,191 dB; VSWR = 1.366; gain = 5.142 dB and directivity = 9.829 dBi.

In recent years, the study of microstrip patch antennas has witnessed significant advancements, offering numerous advantages and promising prospects compared with conventional antennas. These antennas are characterized by their lightweight compact size, low cost, low profile, small dimensions, and excellent conformability. Additionally, microstrip patch antennas exhibit various desirable features, such as dual and circular polarization, dual-frequency operation, broad bandwidth, flexible feedline configurations, and beam-scanning omnidirectional patterns. In this paper, a microstrip patch antenna design tailored for the 2.4 GHz frequency band is proposed, showcasing its potential for applications in wireless communication devices. The antenna is engineered to operate across multiple bands, including the wireless device band, Ultra Wide Band (UWB), and X band. It has a truncated rectangle shape with additional stubs, whereas the substrate material employed is FR4. The resulting design achieves resonance at four different frequencies, effectively covering the Microwave Access (WiMAX) band at 2.5 GHz and 4 GHz. Notably, the implementation of Digital Global Systems (DGS) plays a crucial role in reducing the antenna size while simultaneously enhancing its performance. The proposed microstrip patch antenna demonstrates great potential for meeting the increasing demand of modern wireless communication devices. Its multiband operation, compact size, and improved performance, achieved through the integration of DGS, make it a promising candidate for various wireless communication applications.

The trend of research on microstrip antennas in the millimeter frequency range has been hotly discussed in recent years. With the aim of increasing the bandwidth, beam gain and return loss in accordance with the standards of 5G needs in a fairly small dimension and low complexity. Previously, several studies of microstrip antennas with conventional patches have been carried out, then followed by a triangular array patch model. The antenna designed using Duroid 5880 substrate with a thickness of 1.575 mm and a dielectric constant value of 2.2 was simulated using Computer Simulation Technology (CST) software. The simulation results work at a frequency of 28 GHz with a return loss value of -26.98 dB, VSWR 1.09, gain 8.8 dB, HPBW value of 25.6° and main lobe of 21.0 dBi. This antenna can work well on millimeter wave range for 5G technology. Compared with previous studies of microstrip antennas, this triangular array patch antenna provides better measurement results.
