In this paper we have designed and analyzed step impedance resonator based ultra wide-band (UWB) band pass filter using plasmonic MIM waveguide. The UWB band pass filter has been designed by introducing a shot-circuited stub to implement the shunt inductance between two quarter wavelength (λ/4) step impedance resonators. There is a strong coupling between the stubs. The plasmonic UWB band pass filter has been designed at E band (1360-nm to1460-nm) optical wavelength. The band width of plasmonic ultra wide-band band pass filter is very effective compared to narrow-band band pass filter. The reflection and transmission characteristics, variation of reflection and transmission coefficents by varying the dimensions of UWB, field distribution of plasmonic UWB has been realized using full wave simulation by using commercially available CST microwave studio software. The UWB band pass filter can further used for the development of photonic integrated circuits (PICs).

A new topology of miniaturized interdigital structuremicrostrip planar bandpass filter for Ultra-Wideband (UWB) frequency has been discussed in this paper. The proposed design and its simulation have been carried out by using an electromagnetic simulation software named CST microwave studio. The Taconic TLX-8 microwave substrate has been used in this research. The experimental result and analysis have been performed by using the microwave vector network analyzer. The experimental result showed that the -10dB bandwidth of the filter is 7.5GHz. The lower and upper corner frequencies of the filter have been achieved at 3.1GHz and 10.6GHz respectively. At the center frequency of 6.85GHz, the -1dB insertion loss and the -7dB return losshave been observed. The simulated and experimental results are well agreed with a compact size filter of <br />19×21×0.5mm3.<br /><br />

UWB technology- (operating in broad frequency range of 3.1–10.6 GHz) based filter with WLAN notch has shown great achievement for high-speed wireless communications. To satisfy the UWB system requirements, a band pass filter with a broad pass band width, low insertion loss, and high stop-band suppression are needed. UWB filter with wireless local area network (WLAN) notch at 5.6 GHz and 3 dB fractional bandwidth of 109.5% using a microstrip structure is presented. Initially a two-transmission-pole UWB band pass filter in the frequency range 3.1–10.6 GHz is achieved by designing a parallel-coupled microstrip line with defective ground plane structure using GML 1000 substrate with specifications: dielectric constant 3.2 and thickness 0.762 mm at centre frequency 6.85 GHz. In this structure aλ/4 open-circuited stub is introduced to achieve the notch at 5.6 GHz to avoid the interference with WLAN frequency which lies in the desired UWB band. The design structure was simulated on electromagnetic circuit simulation software and fabricated by microwave integrated circuit technique. The measured VNA results show the close agreement with simulated results.

A novel reconfigurable filter antenna with three ports for three dependent switchable states for impulse radio-ultrawideband (IR-UWB)/wireless local area network (WLAN)/worldwide interoperability for microwave access (WiMAX) applications is presented in this paper. Three positive-intrinsic-negative diodes, controlled by direct current, are employed to realize frequency reconfiguration of one ultra-wideband state and two narrowband states (2.4 GHz and 3.5 GHz). The time domain characteristic of the proposed antenna in the ultra-wideband state is studied, because of the features of the IR-UWB system. The time domain analysis shows that the reconfigurable filtering antenna in the wideband state performs similarly to the original UWB antenna. The compact size, low cost, and expanded reconfigurable filtering features make it suitable for IR-UWB systems that are integrated with WLAN/WiMAX communications.

An ultra-wideband (UWB) bandpass filter (BPF) with a fractional bandwidth (FBW) of about 110%, transmission zero at the high-frequency edge, and band notches at the worldwide interoperability for microwave access (WiMAX) and radio frequency identification (RFID) band is presented in this paper. The filter is based on single short-circuited stub, U-shaped defected ground structure (DGS) array, two U-shaped resonators and two stepped impedance resonators (SIRs). The filter is compact and exhibits a selective filtering characteristic equivalent to a three-pole Chebyshev filter. The design procedure has been described and verified by full-wave electromagnetic (EM) simulation and measurement. The proposed filter has low insertion loss, sharp rejection, and excellent in and out band performance. Due to its applications in WiMAX and RFID systems, the filter may be subjected to high EM radiation from the antenna and nearby sources. Therefore, susceptibility study of such a filter is very important. Hence, the susceptibility study of the band-notched UWB BPF has been carried out by subjecting the structure to an interference source.

This paper investigates the time-domain performance of a switchable filter impulse radio ultra-wideband (IR-UWB) antenna for microwave breast imaging applications. A miniaturized CPW-fed integrated filter antenna with switchable performance in the range of the Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Local Area Network (WLAN) bands could operate well within a 3.0 to 11 GHz frequency range. The time-domain performance of the filter antenna was investigated in comparison to that of the designed reference wideband antenna. By comparing both antennas’ time-domain characteristics, it was seen that the switchable filter antenna had good time-domain resolution along with the frequency-domain operation. Additionally, the time-domain investigation revealed that the switchable filter wide-band antenna performed similarly to the reference wide band antenna. This antenna was also utilized for a tumor detection application, and it was seen that the switchable filter wide-band antenna could detect a miniaturized irregularly shaped tumor easily, which is quite promising. Such an antenna with a good time-domain resolution and tumor detection capability will be a good candidate and will find potential applications in microwave breast imaging.

This paper presents the bandwidth enhancement and frequency scanning for fan beam array antenna utilizing novel technique of band-pass filter integration for wireless vital signs monitoring and vehicle navigation sensors. First, a fan beam array antenna comprising of a grounded coplanar waveguide (GCPW) radiating element, CPW fed line, and the grounded reflector is introduced which operate at a frequency band of 3.30 GHz and 3.50 GHz for WiMAX (World-wide Interoperability for Microwave Access) applications. An advantageous beam pattern is generated by the combination of a CPW feed network, non-parasitic grounded reflector, and non-planar GCPW array monopole antenna. Secondly, a miniaturized wide-band bandpass filter is developed using SCSRR (Semi-Complementary Split Ring Resonator) and DGS (Defective Ground Structures) operating at 3–8 GHz frequency band. Finally, the designed filter is integrated within the frequency scanning beam array antenna in a novel way to increase the impedance bandwidth as well as frequency scanning. The new frequency beam array antenna with integrated band-pass filter operate at 2.8 GHz to 6 GHz with a wide frequency scanning from the 50 to 125-degree range.

During the last two decades, radar, remote sensing, and imaging applications have all made use of ultra-wide band (UWB) technology. UWB systems are susceptible to interference from narrowband signals, hence this work provides a single-notch antenna for the UWB system. There are two stages to the design process. After creating the baseband antenna, it is necessary to create a notched band UWB antenna by carving a slot into patch antenna. In the UWB range (3.1-10.6) GHz, the UWB antenna has the dimensions of 20x30 mm with substrate thickness 1.6 mm made from FR4 lossy. The design relative permittivity was 4.3, a rectangular patch with a portion of the ground is used in the design. A typical slot-shaped resonator is connected to the patch to reject a frequency band (3.273-3.81) GHz which is a world interoperability for microwave access (WiMAX) to solve the problem of the interference with other bands in UWB system For WiMAX applications. The suggested UWB filter will achieve notch band response centered at the resonance frequency of 3,4 GHz. Analysis CSTS v2020 software was used to carry out the simulation. Priority should be given to what has been learned rather than what has been accomplished.

Inherently UWB (Ultra Wideband) communication systems comes with interference problem with some if the existing narrowband communication systems. These bands are stopped with the help of band-stop filter in order to reduce electromagnetic interference However, the complexity and limitations are increased due to these filters, hence this solution is turned down in those applications where design complications and complexity is of concern. Introducing various slots of specific shapes and exact dimensions however, have solved this issue for the researchers around the world. This paper presents a hexagonal PMA (Printed Monopole Antenna) with triple stop bands. The antenna is used for UWB application. The antenna is stopped the WiMAX (Worldwide Interoperability for Microwave Access), WLAN (Wireless Local Area Network) and ITU (International Telecommunication Union) bands. The antenna dimensions are 30x28x16 mm3. FR4 is used between ground and radiating patch with relative permittivity of 4.4. The VSWR (Voltage Standing Wave Ratio) is less than 2 between 3-11 GHz except WiMAX (3.1-3.7 GHz), WLAN (5.1-5.8 GHz) and the ITU frequency band (7.95-8.4 GHz). The antenna is design in CST software.

Wireless communication demands better channel capacity with a high data rate in the modern era. To fulfill these demands, the MIMO-communication systems are developed that use manifold antennas for transmitter and receiver end. MIMO is a state-of-art technology that improves the reliability of the communication systems by utilizing the diversity technique to mitigate the multi-path fading issues, where signals may come together belligerently at the receiver. Improve spectral efficiency is achieved by the total transmitted power spreading over the antennas. Thus, MIMO can increase channel capacities as well as the reliability of the communication system without sacrificing extra transmitted power or power spectrum. Several MIMO antennas have been designed in the literature to improve their characteristics in terms of impedance bandwidth; miniaturization & isolation improvement. The MIMO-communication systems with THz range are required for high data speed in Terabit/sec (Tbps). Also, it is providing very high throughput per device (from multiple Gbps to several Tera-bps) including per area efficiency (bps/km2). It is also predicted that the world monthly traffic in smartphones will be about 40 Peta-bytes in 2021, so the demand for MIMO antennas will be increased in the future. In this thesis, various microwave components for the MIMO wireless communication system has been analyzed and designed. Three major components designed and analyzed in this thesis are 1. MIMO Antennas 2. Metamaterial Absorber 3. UWB Microwave Filter MIMO Antennas: In this thesis, various MIMO antennas for UWB, SWB, and Multiband applications have been designed. Various decoupling techniques to avoid the v interference between antenna elements are designed which enhancing the diversity parameters with improved channel capacity for modern wireless applications. To mitigate the interference between bands and to improve the reliability of the signals, a notch characteristic has been introduced. SAR analysis also discusses in this thesis with the human head and confirms that proposed MIMO antennas are in the acceptable range with 1g and 10g of bio tissues given by FCC and EU for mobile and other near field applications. All the MIMO antennas with different frequency characteristics are discussed in Chapter-2 to Chapter-6. Metamaterial Absorber: To improve the isolation level in MIMO antennas as well as to minimize the Radar Cross Section (RCS) and Electromagnetic Interference (EMI), a design of multiband metamaterial absorber (MMA) for X-band applications has been suggested. This MMA provides three high absorbance bands at 8.2GHz, 9.45GHz, and 12.45GHz with 99.4%, 96.4%, and 91.25% absorbance respectively. Proposed MMA is polarization insensitive in all three bands with minimum RCS -33.2dBm2. This absorber structure has designed on FR-4 (4.4) substrate having tanδ = 0.02 with unit cell dimension 20×20×1mm3. So the proposed absorber is found appropriate for stealth aircraft, RCS and EMC reduction, isolation in MIMO antenna, imaging, and sensing in the X-band applications, discussed in Chapter-7. UWB Microwave Filter: In this research work, the design of the UWB filter with extended stopband characteristics by using a parallel-coupled line, open-ended line, multimode resonator (MMR), and defected ground structure (DGS) has been presented. This filter provides good return and insertion loss in the passband (3.1-10.6GHz) as well as stopband (10.8-18GHz). The group delay of the filter is almost constant throughout the passband. Detailed analysis of supportive coupled, feeding, and the open-ended line is vi verified with equivalent circuits. The prototype of the filter is compact as 22×20mm2 with a 109% fractional bandwidth. The proposed filter is suited for recent weather reporting Radar, Imaging, and Satellite receiver systems because simulated results have good agreement with measured results as discussed in the Chapter-8. RESEARCH OBJECTIVES: The major objectives of the research work are listed below: 1. To enhance the impedance bandwidth of the MIMO antenna and microstrip filter for various wireless applications. 2. To design and analyze the circularly polarized MIMO antenna for GPS, vehicular and 5G applications. 3. To enhance the isolation between the various elements of the MIMO antenna, to improve the various diversity parameters. 4. To enhance the specific absorption ratio (SAR) performance of the MIMO antenna for a handhold and mobile applications. 5. To design a Metasurface for stealth and isolation improvement in MIMO antenna applications.

The thesis divides into three types: (a) design of the UWB filters; (b) microwave measurements of the dielectric materials and (c) design of the integrated UWB filter. I first design and fabricate several UWB filters on PCB substrate. The compact pseudo-interdigital ultra-wideband filter (PIDT-UWBF) using the tapped input/output (I/O) and strong coupling is designed and implemented on FR4 substrate. The compact three-poles hairpin line wideband bandpass filter (HL-WBF) with several embedded open stubs to improve the stopband is designed and implemented on print circuit board (PCB) substrate. The high performance hairpin line diplexer for the direct sequence ultra-wideband communication is designed and implemented. Experimental results also show a good agreement with the simulated results. In addition, I have developed a novel finite ground coplanar waveguide (FG-CPW) to precise measure the microwave properties of silicon substrates without a thin SiO2 buffer layer. The dielectric constant and the characteristic impedance were extracted from calibrated measurements made at up to 20 GHz using the FG-CPW method. The loss tangent was then obtained by the conformal mapping approach after the dielectric constant and characteristic impedance had been accurately extracted. Finally, I fabricated a compact and high performance integrated coplanar waveguide UWB filter on high resistivity silicon (HRS) substrate at millimeter wave. The equivalent circuit model is also developed to predict the filter performances corresponding with structural dimensions. This filter at center frequency f0 of 27.4 GHz has presented very good measured characteristics including the low insertion loss, sharp rejection, wide bandwidth and low group delay. Experimental results of the fabricated filter show a good agreement with the predicted results. Thus, the proposed passive component is useful at the wafer level for compact millimeter-wave UWB systems.

In recent years, the wireless industry has witnessed tremendous development for the defense and commercial segments. The explosive growth in the modern radio frequency and microwave systems leads to an increased interest in the research of miniaturized microwave circuits with superior performance. Broadband components, in particular band pass filters (BPFs) and couplers are some of the widely used components in the modern communication systems, software defined radios, cognitive radios, imaging systems and positioning radars. In order to meet these requirements, the use of innovative geometries, a thorough understanding of their behavior by appropriate analytical techniques and the use of appropriate fabrication approaches are essential. This thesis is an effort in this direction. In this thesis work, an aperture in the ground plane is used to achieve the tight coupling in the edge and broadside-coupled coupled lines which may be otherwise difficult due to the fabrication limitations. Since microstrip lines with an aperture in the ground plane are found to be very useful in various MIC and MMIC components, closed form analytical expressions developed here will be useful for their initial synthesis. The performances of components using these are enhanced using open/short circuited resonators, spurlines and stubs. A quasi-static approach has been investigated to obtain simple closed form expressions for a microstrip line with a rectangular aperture in the ground plane. The effect of a rectangular aperture in the ground plane has been incorporated in the commonly used expressions of a regular microstrip line by introducing the concept of an equivalent effective height. The expressions for the effective height microstrip geometries with defected ground are obtained and this has been further extended to various possibilities of two-conductor and three-conductor coupled lines. Analysis of the filters and the couplers are mainly based on the even and odd mode propagation characteristics of coupled lines. This approach is extended in this thesis for three conductor coupled lines. Novel broadband BPFs and couplers and dual band pass filters employing various coupled line configurations and defected ground have been developed in this research work. Most of these components have been implemented on a regular microwave laminate or LTCC medium (planar or multi-layer) and tested for the required RF performances. The experimental results were compared against the analytically computed results based on the circuit models and the full wave simulations using electromagnetic (EM) simulations for the validation. The results are in good agreement. With practical requirements of the organization in mind, additional design elements such as open circuit stubs have been incorporated in some of these designs to achieve the desired performance. It is expected that the wideband filter (3.0GHz to 3.8GHz) and the broadband coupler (4GHz to 6GHz) developed in this thesis work would be deployed in systems developed at the Central Research Laboratory, Bharat Electronics Limited, Bangalore, India. In summary, the present doctoral work strives to (i) establish a simplified analysis method for the microstrip lines and coupled microstrip lines with a rectangular aperture in the ground plane, (ii) extend the even and odd mode analysis of the coupled lines for several new coupled line configurations, (iii) design novel broadband microwave filters, dual band filter and couplers using both these, (iv) fabricate these devices using the planar technologies including LTCC, and (v) validate the analysis and design with important practical applications.
