Back aperture
This document summarizes a research paper about the development of a ground plane aperture technique to enhance capacitive coupling in parallel-coupled microstrip lines (PCMLs) and enable the design of broadband multi-pole microstrip bandpass filters. The technique involves forming an aperture in the ground plane of the PCML. Equivalent circuit models of the PCML indicate that the aperture increases the coupling factor in a frequency-dependent manner. A novel multi-pole broadband filter topology is proposed using a single microstrip line resonator connected between two PCML sections. Predicted and measured results confirm attractive properties such as 60% bandwidth, deep stop-band rejection, and compact size.

Design and comparison of printed antennas using meander line technique
The interest for compact antennas in wireless communication increase due to the portability and mobility of the communication devices. Generally, an antenna at low frequency exhibits in large physical size. This project investigates the design of an antenna at 400 MHz. The simulation of the antenna has been performed using CST MWS. Since medical applications are dealing with low frequency, it will lead to large size of antenna which brings a challenge for wireless personal area network (WPAN). It is well known that the antenna performance decreases (according to Chu’s equation) as the size of antenna decreases. Therefore, antenna miniaturization using Meander Line (ML) will be taking place to overcome the challenges. Thus, this paper presents a comparison between i) printed dipole antenna without meander line technique, ii) printed dipole with meander line technique and iii) printed monopole antenna with meander line technique. The results show that an estimation of reduction size by 50% can be achieved using Meander Line technique.

The array has a voltage standing wave ratio (VSWR) working bandwidth (BW) of 13.258 GHz between 3.394-16.652 GHz, with a fractional BW (FBW) of 132.28% with respect to a center frequency of 10.023 GHz. The two elements of the MIMO array are 900 polarizations mismatched for better isolation. Consequently, less than 20 dB of isolation has been achieved throughout the entire BW. Also observed was a good combined realized peak gain of up to 5.85 dBi and total efficiency of greater than 85%. For MIMO performance key parameters, the array exhibits the envelope correlation coefficient (ECC) <0.0033, diversity gain (DG) >9.983, total active reflection coefficient (TARC) <0.445, mean effective gain difference (MEG12) ≈0 dB, and the channel capacity loss (CCL) <0.4 bps/Hz.

Rectangular microstrip array antennas for wide triple band operation
This document presents the design and experimental results of three rectangular microstrip array antennas - TERMAA, MGTERMAA, and CTGTRMAA - for wide triple band operation. TERMAA achieves triple band operation with omni-directional radiation patterns. MGTERMAA obtains quadruple bands by minimizing the ground plane area. CTGTRMAA further enhances the impedance bandwidth in the triple band operation without changing the radiation characteristics by truncating the corners of the minimized ground plane. The gain is also increased from 0.71 dB to 3.90 dB. The proposed antennas could find applications in wireless systems operating in the WLAN, HIPERLAN/2, and X to Ku bands.
Design and development of microstrip array antenna for wide dual band operation
This document summarizes the design and development of a microstrip array antenna for wide dual band operation. Specifically, it presents a novel design of a slot loaded two element rectangular microstrip array antenna (SRMAA) that achieves triple band operation. By minimizing the ground plane to 48.8% and 76.8%, the antenna is able to convert to dual band operation while enhancing impedance bandwidth and gain without significantly changing the omni-directional radiation pattern. Experimental results show the proposed antenna designs achieve their design goals of dual band operation and performance improvement over traditional designs.
Broad Band Micro strip Patch Antenna Design-a Critical review
This document provides a review of techniques for designing broadband microstrip patch antennas. It discusses how microstrip patch antennas inherently have narrow bandwidths, and various techniques that have been used to enhance the bandwidth in recent decades.

The review then examines specific examples from literature on compact circularly polarized patch designs using slots, and UWB designs using parasitic elements and slots. Overall, the document aims to critically review different approaches for fabricating microstrip patch antennas with broader bandwidths.

Design of Ku-band power divider using Substrate Integrated Waveguide technique
A Ku-band Substrate Integrated Waveguide power divider is proposed. In this work, the SIW power divider is designed with T-junction configuration. The SIW technique enables the power divider to have low insertion loss, low cost and features uniplanar circuit. An additional of metallic via hole is added in the center of the junction to improve the return loss performance of the Tjunction SIW power divider. The simulated input return losses at port 1 are better than 27 dB, and features equal power division of about -3.1 dB ±0.4 dB at both output ports across frequency range of 13.5-18 GHz. The SIW power divider is fabricated, and the measurement results show acceptable performances. Since there are some losses contributed by the SMA connector of the fabricated SIW power divider prototype, an additional SIW transmission line is simulated and fabricated to analyze the connector loss.

This document presents the design and experimental results of three rectangular microstrip array antennas - TERMAA, MGTERMAA, and CTGTRMAA - for wide triple band operation. TERMAA achieves triple band operation with omni-directional radiation patterns. MGTERMAA obtains quadruple bands by minimizing the ground plane area. CTGTRMAA further enhances the impedance bandwidth in the triple band operation without changing the radiation characteristics by truncating the corners of the minimized ground plane. The gain is also increased from 0.71 dB to 3.90 dB. The proposed antennas could find applications in wireless systems operating in the WLAN, HIPERLAN/2, and X to Ku bands.
Design and development of microstrip array antenna for wide dual band operation
This document summarizes the design and development of a microstrip array antenna for wide dual band operation. Specifically, it presents a novel design of a slot loaded two element rectangular microstrip array antenna (SRMAA) that achieves triple band operation. By minimizing the ground plane to 48.8% and 76.8%, the antenna is able to convert to dual band operation while enhancing impedance bandwidth and gain without significantly changing the omni-directional radiation pattern. Experimental results show the proposed antenna designs achieve their design goals of dual band operation and performance improvement over traditional designs.
Broad Band Micro strip Patch Antenna Design-a Critical review

It discusses how microstrip patch antennas inherently have narrow bandwidths, and various techniques that have been used to enhance the bandwidth in recent decades. These techniques include using shorting pins, slot loading on patches, planar meta-material unit cells, and conductive biasing. The review then examines specific examples from literature on compact circularly polarized patch designs using slots, and UWB designs using parasitic elements and slots. Overall, the document aims to critically review different approaches for fabricating microstrip patch antennas with broader bandwidths.
(Ofdm)
OFDM (Orthogonal Frequency Division Multiplexing) is a digital modulation technique that divides the available spectrum into multiple orthogonal subcarriers. It has become popular for digital communication systems due to its ability to mitigate multi-path interference through the use of a guard interval between symbols. OFDM allows for high bandwidth efficiency by overlapping subcarriers and its implementation has been enabled by advances in DFT and LSI technology.

Design of Ku-band power divider using Substrate Integrated Waveguide technique
A Ku-band Substrate Integrated Waveguide power divider is proposed. In this work, the SIW power divider is designed with T-junction configuration. The SIW technique enables the power divider to have low insertion loss, low cost and features uniplanar circuit. An additional of metallic via hole is added in the center of the junction to improve the return loss performance of the Tjunction SIW power divider. The simulated input return losses at port 1 are better than 27 dB, and features equal power division of about -3.1 dB ±0.4 dB at both output ports across frequency range of 13.5-18 GHz. The SIW power divider is fabricated, and the measurement results show acceptable performances. Since there are some losses contributed by the SMA connector of the fabricated SIW power divider prototype, an additional SIW transmission line is simulated and fabricated to analyze the connector loss.

Simulation and optimization of tuneable microstrip patch antenna for fifth-ge...
Microstrip patch antennas (MPAs) are known largely for their versatility in terms of feasible geometries, making them applicable in many distinct circumstances. In this paper, a graphene-based tuneable single/array rectangular microstrip patch antenna (MPA) utilizing an inset feed technique designed to function in multiple frequency bands are used in a fifth-generation (5G) wireless communications system. The tuneable antenna is used to eliminate the difficulties caused by the narrow bandwidths typically associated with MPAs. The graphene material has a reconfigurable surface conductivity that can be adjusted to function at the required value, thus allowing the required resonance frequency to be selected. The simulated tuneable antenna comprises a copper radiating patch with four graphene strips used for tuning purposes and is designed to cover a wide frequency band. The proposed antenna can be tuned directly by applying a direct current (DC) voltage to the graphene strips, resulting in a variation in the surface impedance of the graphene strips and leading to shifts in the resonance frequency.

This paper presents a novel approach for completely test enable feature and low-voltage delta– sigma analog-to-digital (A/D) converters for cutting edge wireless applications. Oversampling feature of ADCs and DACs is enough to meet the requirement related to in-band and adjacent channel leakage ratio (ACLR) execution of 3G/4G portable radio. The quantization noise which is not filtered in ADC is addressed. We have achieved work power-optimization and test enable feature of oversampling ADC is uses in design and simulation so that the problem of quantization error in continues time sigma delta ADC is solved. This paper suggests support to designer for selecting appropriate topologies with various channel arrangements, number of bits and oversampling issues. A test enable feature of CT A/D is presented introducing the test signal generation (TSG) and the COrdinate Rotation Digital Computer (CORDIC) for evaluating the performance of ADC. This helps in addressing the challenge of 4G and upcoming 5G wireless radio. System level plan of a delta–sigma modulator ADC for 4G radios is studied.

In this paper, a tuneable rectangular microstrip patch antenna (MPA) is simulated and optimized to operate in four frequency bands of the next generation of wireless communication systems. The proposed design incorporates a copper radiating patch with four implanted graphene strips for tuning purposes. The reconfigurable surface impedance of graphene can easily be altered by applying a DC voltage bias directly to the graphene strips, allowing the operating frequency of the antenna to be tuned as desired. The capability of the applied voltage to tune the operating frequency band of the proposed antenna is studied via computer simulation technology (CST) microwave studio (MWS). Frequency selective surfaces (FSSs) are introduced in order to improve the radiation parameters of the antenna. The operating frequency band of the tuneable rectangular MPA increases directly as the applied DC voltage bias is increased. Based on the simulation results, a tuneable rectangular MPA placed between two FSSs is proposed for fifth-generation applications.
