Performance Comparison of Rectangular and Circular Coplanar Textile Antennas

Abstract

This paper presents a comparative study of a rectangular and circular patch antennas above the AMC structure, operating on two 2.4 GHz and 5.8 GHz frequency bands for WLAN applications. This structure is entirely made using textile materials. The results of simulations and measurements are presented to compare the performance of the two antennas. CST Microwave Studio is used to design and compare the performance of antennas. Based on the results found, it has been found that the rectangular patch antenna has a better performance compared to the circular patch antenna. And the proposed antennas have a good performance/size ratio compared to antennas exiting in the literature.
