Various broadband multi-resonator gap-coupled configurations of equilateral triangular microstrip antenna and its compact variation, half equilateral triangular microstrip antenna, are proposed. The broadband proximity fed equilateral triangular microstrip antenna yields bandwidth of more than 650 MHz (~44%), whereas equivalent proximity fed gap-coupled half equilateral triangular microstrip an...

Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system’s printed circuitry. In this project, a 2.4 GHz circular polarization microstrip antenna is designed, constructed and measured. The selected microstrip antenna is a dual –fed circular polarized microstrip antenna. The antenna consists...

Methods for reducing Radar Cross Section (RCS) of objects have been investigated by many researchers both experimentally and theoretically for the last so many years. This chapter presents a chronological review of important research in the fields of RCS studies, RCS reduction techniques and fractal based scattering and radiating structures. This chapter is divided into two sections. The first ...

The paper presents a broadband microstrip patch antenna for wireless communication. In its most basic form, a microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side. The patch is generally made of conducting material such as copper or gold and can take any possible shape. A rectangular patch is used as the main rad...

In this present work, Rectangular Microstrip Patch antenna loaded with symmetrically cut H and hexagonal shaped metamaterial (MTM) is proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.794 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. At 1.794 GHz, the bandwidth is increased up to 27 MHz in compa...

An isolation enhanced dual polarized microstrip patch antenna has been designed for Sband Synthetic Aperture Radar. This antenna operates at 3.125 GHz with operating bandwidth of 150 MHz or 4.8%. The electromagnetic power is coupled from the feed line to radiating patch through proximity coupling feeding technique for better bandwidth achievement. A centre groundshorted microstrip line is creat...

Microstrip patch antennas are light weight and low profile antennas so use of these kind of antennas are more easy in portable and small communication devices where size is concerned . In this paper the analysis of T –slot rectangular microstrip patch antenna is presented. The antenna is designed for wide applications in C-band space communication and wireless LAN communication systems. The ban...
