Abstract

The performance of the TM/sub 02/-mode circular patch antenna with two superstrate layers has been investigated and a typical design of such antenna was carried out. The method of moment full-wave electromagnetic analysis and design package Ensemble for stratified material layers is used as the design tool. It is shown that the antenna pattern exhibits minimum radiation in the zenith direction and is fairly symmetrical in azimuth, which is suited for wireless LAN application. With the two superstrate layers, the maximum gain of the antenna increase, and by tuning the thickness of the superstrate layers, the elevation angle of the maximum gain can be changed to suit the various wireless LAN applications.
