Résumé :
A Co planner Wave Guide (CPWG) fed with octagonal patch antenna is modified from their respective rectangular patch are presented for WLAN application. The dielectric material applied in the design process for both co planar and micro strip patch antenna is FR4 Epoxy Glass, which has relative permittivity of 4.4 and substrate height 1.6mm. Antenna parameters used to check the performance. A comparison is made between the octagonal co-planar antenna and octagonal micro strip antenna available. Ansys HFSS is used for antenna design and analysis. Both designed antennas are suitable for wireless local area network application and the design parameters of the antenna are optimized to resonate at 3GHz frequencies for WLAN applications. It has been found that octagonal micro strip patch antennas have lower return loss and are more directive than co planar patch antenna. High directivity of octagonal micro strip antenna is due to the presence of ground plane under the substrate of antenna. The results obtained by simulations have also shown that octagonal co planar patch antennas have high radiation efficiency (a measure of the power radiated through the antenna as an electromagnetic wave to the power fed to the antenna terminals) and which implies a wider bandwidth as compared to an octagonal micro strip patch antennas. The radiation efficiency obtained for micro strip patch antenna is 24% and that for co planar patch antenna is 67%, the directivity for micro strip patch antenna is 3.75 dB and that for a co-planar patch antenna is 3.25 dB.

Where the existing design focuses only on frequency reconfiguration, but it does not take advantage of the entire frequency and power spectrum. Therefore, the honeycomb-shaped Metamaterial cells used in the suggested antenna design serve as a superstrate for micro-strip patch antennas with a extensive range of actual negative permittivity and permeability, as well as a refractive index feature.

Also, the superstrate layers serve as a random, providing strength to the entire structure while also improving other antenna metrics such as gain and bandwidth. The design outputs for several metamaterial superstrates in terms of reflection coefficient (S11), gain, and bandwidth are compared by adding varactor diode switches to the metamaterial superstrate, which also allows for frequency reconfiguration. As a result, the suggested antenna was designed to reduce mutual coupling and improve system performance in 5G technology, specifically in mm-wave applications. The obtained results for metamaterial superstrate designs demonstrate high bandwidth and gain behavior.

Résumé :
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.

Résumé :
This paper analyzed the type of mini-type antenna, studied the miniaturization technique based on simulation in depth, and finally designed the high-performance micro-strip antenna. The advantages of micro-strip antenna are light-weight, compact size, relatively thin thickness, and so on. However, it still needs aggressive miniaturization to satisfy the requirements of encapsulation. Techniques for miniaturization of antenna mainly include a ground plane, double-layer patch, shorting pin or wall, lossless dielectric substrate and the spiral structure. The techniques of multi-layer and shorting wall can narrow down the resonant frequency and attain bandwidth enhancement. Nonetheless, they have a complicated structure. Thus, simulation researched the influence of the surrounding tissue in detail, the position relation of shorting pin and the feed point, the substrate parameters and the structure parameters of the spiral antenna on performance. At last, through the techniques of the shorting pin, high permittivity substrate and the spiral shape, two Archimedean micro-strip patch antennas were developed for wireless capsule endoscope. The antenna has the bandwidth of about 300 MHz, the minimum voltage standing-wave ratio of 1.14:1, and the diameter of 8.3 mm. Therefore, the antenna can offer excellent performance for transmitting image data.

In this paper, we present a single feed circularly polarized microstrip patch antenna operating at 2.4 GHz WLAN frequency. A typical microstrip patch antenna is fabricated on a metal coated dielectric substrate where the metallic antenna patch is defined on the top of the substrate, whereas the bottom of the substrate acts as a ground plate. These antennas are typically used for civil and military communication purposes. Before fabrication, the presented antenna was first designed, simulated and optimized in CST Microwave studio. The circular polarization was achieved by perturbation of the edges, making the design optimization a bit challenging. The simulated and measured return loss of the proposed antenna is -27 dB and -13.34dB, respectively. Whereas, the gain came out to be 6 dB. The obtained results show that the presented antenna has the quality of right hand circular polarized antenna.

For modern wireless communication systems, miniaturized multiband antennas with enhanced bandwidth and gain are desired to achieve optimum system performance. A planar microstrip patch antenna is preferred because of its small size, low cost, and ease of fabrication. For impedance matching, a conductive metallic patch can be fed by different techniques to deliver the maximum power to the microstrip antenna. The various configurations of inset feed, co-axial feed, aperture feed, and proximity feed, and CPW feed, which are used to excite micro-strip patch antennas, are reviewed in this research paper.

A composite Global Positioning System (GPS) patch antenna with a quadrature 3 dB hybrid coupler was designed and implemented for working RHCP and had a broadband axial ratio (AR) bandwidth. We designed two patches as a FR-4 patch and 1.5 mm thickness thin ceramic patch with a quadrature 3 dB hybrid coupler. A CP radiation pattern was achieved, and the AR bandwidth improved by incorporating a quadrature 3 dB hybrid coupler feed structure in a micro-strip patch antenna. SMD by chip elements was applied to the quadrature 3 dB hybrid coupler. For the composite FR-4 and ceramic patch antennas, the VSWR measurement showed a 2 : 1 ratio over the entire design band, and the 3 dB AR bandwidth was 295 and 580 MHz for the FR-4 patch and ceramic patch antennas, respectively. The antenna gains for the composite FR-4 and ceramic patch antennas were measured as 1.36–2.75 and 1.47–2.71 dBi with 15.11–25.3% and 19.25–28.45% efficiency, respectively.

Résumé :
Antennas are a difficult component to design, yet they play critical functions in wireless transmission systems. To construct the required antenna, the antenna designer must overcome enormous challenges in getting all of the antenna's optimal qualities. Antenna designers must consider antenna factors like bandwidth, return loss, VSWR, gain, directivity, efficiency, and so on, for specific applications. So keep all parameter values as optimal as possible; sometimes you may need to adjust the design of the antenna from its standard shape. The present investigation describes the development of a partial ground-plane micro-strip patch antenna in the shape of a minaret for use in lower 5G and Wi-MAX networks. A microstrip patch antenna with a minaret-shaped radiating element and a partial ground plane is suggested. The suggested antenna is simple because it does not include any unwanted components on the patch, yet the significant gain is maintained by optimizing the ground plane's dimensions and position. The proposed antenna is constructed using a Rogers RT5880 (lossy) substrate, the line feeding method, and 0.035 mm thick (annealed) copper for the patch and ground components. CST Studio Suite 2018 is used for layout and modelling. The antenna is 28 x 16 x 0.79 mm3 and offers a maximum gain of 2.321 dB and a maximum directivity of 2.529 dBi. The recommended antenna has a frequency range of 3.3721 GHz to 4.2382 GHz, making it usable for both low-band 5G and Wi-MAX systems.

Résumé :
Abstract: Microstrip patch antennas are predominantly in use in mobile communication and healthcare. Their performances are even improved, using Split-Ring Resonator cells. But finding the ideal dimensions of the microstrip patch antenna and calculating the correct number and size of the split ring resonator cells consume a lot of time when we use Electromagnetic Simulation software to design first and then simulate. Using the pre-calculated results of certain sets of microstrip patch antennas with split ring resonators, a machine learning model can be trained and hence be used to predict the antenna metrics when the dimensions are specified. When the machine learning algorithms are combined with feature-optimization algorithms such as the Genetic Algorithm, the efficiency and performance can be improved further. Keywords: Machine Learning, Micro-strip Patch Antenna, Genetic algorithm, Split Ring Resonator.

Ultra-wideband (UWB) technology has become influential among academic research and industry because of its vast application in the wireless world. However, several drawbacks have in UWB based antenna. To tackle this, EBG (Electromagnetic Band Gap) structures have proposed. Furthermore, the design of EBG structures is very complex due to the uncertain EBG properties dependence upon unit cell parameters. Therefore, to the optimal design of micro strip antenna for applications of UWB, EBG-PIO (pigeon inspired optimization) on the basis of micro strip patch antenna has been proposed to enhance micro strip antenna’s performance in terms of directivity, gain, bandwidth and efficiency. To select design parameters optimally, the PIO technique is proposed with substrate material of Rogers RT/Duroid 6010 with height h = 1.6 mm. Proposed antenna return loss remains –34.6 dB to cover applications of UWB (3.1–10.6 GHz). Also, results exhibited by both proposed technique and fabricated model-based antenna has outperformed than existing techniques regarding directivity, return loss, bandwidth, gain and radiation efficiency.

Résumé :
Double Elliptical Micro-strip Patch Antenna (DEMPA) is developed out of Double Elliptical Patch (DEP) which is a recently proposed shape of patch. The use of DEP results in higher flexibility in design of patch antenna and thus promotes antenna miniaturisation. The present work is an attempt to demonstrate the miniaturisation of radiolocation antenna through the concept of Design Flexibility (DF). In this paper, optimised neural network model for synthesis of DEMPA has been developed for radiolocation applications for which the earmarked frequency band is 8.50 GHz – 10.50 GHz. With the help of synthesis model, for an arbitrary operational frequency of 9.85 GHz, radiolocation antennas with effective patch area ranging from 142 mm2 to 66 mm2 were designed by using DEPs. In this case, the percentage reduction in effective patch area was found to be 53.52%. It shows that double elliptical patches can be employed to develop miniaturised radiolocation antennas. One prototype antenna was fabricated and tested to demonstrate the efficacy of the methodology adopted. The fabricated antenna had resonance at 10.15 GHz with a reflection coefficient of -20.73dB and bandwidth of 3.106 GHz (from 7.458 GHz to 10.564 GHz). Its Fractional Bandwidth was 34.469%. Positive and reasonably good gain was maintained over the entire working band. At resonance, the peak gain was 4.22 dB.The measured characteristics of antenna were in close agreement with the simulated results. The methodology presented in this paper can also be applied to frequency bands for other wireless applications.

For this, multi-band MIMO (multi-input multi output)applications, the antenna design with the target parameters is a challenging task toestablish a rich and reliable wireless communication setup with the monitoring systemin SHM of both biomedical and industrial sectors. Higher SAR will create the hazardsto the human body. The gain of the antenna and return loss figures depends on thesignal loss in the human tissues. Another important design challenge is the antennasize, which should be convenient to carry. Usually, Micro strip patch antenna is usingfor such type of applications as it satisfies most of the design parameters. But thebandwidth and gain of MSP are very limited. Hence there is huge scope to enhancethe gain and bandwidth of the micro strip patch antenna to fit for the biomedicalinvasive applications.
