Abstract :
This paper describes the circular microstrip antenna with an air gap between two substrates and ground plane using the cavity model theory. The gain and bandwidth improvement is achieved using an air dielectric between two substrates. The microstrip patch antenna was fed by line with an air dielectric between two substrates. The gain of this antenna was 2.39 dB greater and bandwidth was 1.35% greater than that of a conventional circular patch antenna. The method of computation uses MOM and this is enabled by FEKO software.
