Analysis of electromagnetic noise mitigation in a mixed signal board consisting of analog to digital convertor (ADC) and low noise amplifier (LNA) is presented. A new approach of mitigating the electromagnetic noise is proposed in the form of complementary split ring resonator (CSRR) loaded right handed (RH) transmission line as an alternative to EBG loaded large power planes. To analyze the effect of electromagnetic noise in mixed signal board, noise coupling power and noise figure at the output of LNA were measured for various periodic configurations (RH transmission line, alternating impedance electromagnetic bandgap (AIEBG), and CSRR loaded transmission line). The noise figure at the output of LNA is 11.5 dB, 2.9dB and 2.7 dB for RH transmission line, AIEBG based power plane and CSRR loaded RH transmission line respectively.

Two-element and four-element sectoral fractal planar monopole antenna arrays for wideband communication applications is investigated. The proposed antenna structure is constructed by means of feeding two and four element omnidirectional Sectoral fractal patch elements with a 3-section 2-way Wilkinson power divider. The peak gain values of two-element and four-element array antennas are almost 3 dB and 6 dB higher than the single-element peak realized gain, respectively.

In this paper, design principles for implementation of broadband T-type and Y-type power divider based on Substrate-Integrated Waveguide (SIW) technology has been presented. Different design curves have been developed based on simulation results and are used to implement 1×2 power dividers of Y-type and T-type. Finally, by cascading T-type and Y-type stages a 1×4 Power divider of equal division is designed and simulated. The proposed design shows a broad bandwidth (-20 dB) of 18.3% and insertion-loss Bandwidth (1%) of 17.86%.

The present work presents gain enhancement using a Diffraction Optical Element (DOE) lens. The design of the lens, made of Rexolite, is discussed. It is placed in front of a radiating antenna and modeled in HFSS and CST. Beam focusing has been illustrated It is shown that the size of the lens is directly proportional to gain increase which can be as high 25 dB enhancement. Nevertheless a more realistic size still results in a 10dB increase at 40 GHz The lens can be easily constructed and experimental validation of simulated results is under progress.

A compact wide band planar textile antenna for broadband application is presented. The increasing demand in wearable personal area networks in civil, medical, sport wear and military domains promise to replace wired communication networks in the near future. Thus, it is a challenging task today to explore body mounted antenna system for various monitoring applications. In this article, we have design a microstrip fed wide band textile antenna which operates from 2.1GHz to 9.1 GHz band. Here, the performance of this antenna in terms of resonance frequency, return loss and radiation pattern is analyzed and measured. The measured results are in good agreement with simulated one.

Analysis of phase characteristics of a transmission lines with capacitive stubs loaded with CSRRs of three different geometries (square, circle and triangle) in the ground plane is presented. The phase delays of -270°, -267° and -263° are observed for CSRRs of square, circular and triangular geometries respectively at resonant frequency of 1.75GHz compared with a reference transmission line (0deg) of same length. A length reduction of approximately 75% is achieved for all three CSRR loaded transmission lines when compared with a conventional transmission line.

In this paper, the CPW fed monopole slot antennas has proposed for Industrial, Scientific, and Medical (ISM) band (2.4-2.48 GHz) biomedical applications. To make the designed antenna suitable for implantation, it is printed on biocompatible Al2O3 ceramic substrate. The proposed antenna was simulated by a phantom liquid and imitating the electrical properties of the human muscle tissue. A study of the understanding of the antenna performance as a function of its dielectric parameters of the environment is presented. Simulations in slot and H-slot are state demonstrate that the antenna covers the complete ISM band. The proposed antenna shows the lower return loss, good impedance matching and high gain compared to other implantable antennas.

A frequency reconfigurable wide slot antenna is presented. The proposed antenna is capable of switching the frequency bands between 1.3 and 2.7 GHz. The antenna has an overall dimension of 70mm × 70mm × 1.6mm, with a wide slot printed on one side of the substrate (RT Duroid5880, εr=2.2). A 50 Ω microstrip line printed on other side of the substrate is used to feed the slot. The antenna resonates at different frequency bands depending upon the feed line length. Hence the frequency re-configurability is achieved by varying the length of the feed line. When the length of the feed line is 30mm antenna resonates at 2.5GHz with an impedance bandwidth of 16% (2.25-2.65 GHz). For the feed line length of 40mm antenna resonates at 1.4GHz with an impedance bandwidth of 22% (1.31-1.62GHz). When the feed line length is changed to 60mm antenna resonates at 2.65GHz with an impedance bandwidth of 3% (2.61-2.69 GHz). The simulated and measured return loss and radiation pattern results for the proposed antenna are presented.
