Aperture coupled microstrip slot antenna

By Editor

An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna

Optimization of Aperture Coupled Microstrip Patch Antennas named Aperture Coupled Microstrip Patch Antenna. This new microstrip antenna demonstrates improvement on the impedance bandwidth from 5% to 50% and 4{5dBi gain enhancement. Due to their structural complexity, it is challenging job to get the expected gain and bandwidth improve-ments. AN APERTURE-COUPLED STACKED MICROSTRIP ANTENNA FOR GPS ... This thesis investigates a technique of stacking rectangular microstrip antenna elements to achieve dual frequency operation. In the particular configuration studied, two square patches are stacked on top of each other above a common ground plane. These elements are fed by the means of an aperture-coupled feed network. The aperture-coupled

The proposed design is based on a new aperture coupling technique in which the slot is fed by a microstrip line and coupled to several parasitic patch radiators etched on the opposite side from the slot. Design and Optimization of Aperture Coupled Microstrip In this paper genetic algorithm has been used for optimization of aperture coupled rectangular microstrip patch antenna (ACMPA) dimensions, It was exactly used to optimize the patch length, the slot dimensions in the ground plane and the dimensions of the feed line.

The aperture coupled microstrip patch antenna feed technique [1] was introduced in 1985 that includes electrically isolated microstrip transmission lines and patch conductors. These structures are electromagnetically coupled through a small aperture in the isolating ground plane (Fig. 1) [1]. Two common feed techniques for patch antennas are ...
