A PROXIMITY FEED DUAL BAND CIRCULAR SHAPED ANTENNA WITH SEMICIRCULAR GROUND PLANE

In this work, we present a Circular Shaped proximity feed Microstrip Patch Antenna. The antenna is comprised of cir-cular shaped radiation patch and this radiating patch is faded by proximity coupling. The ground plane of the antenna has Semicircular pattern to improve the coupling level of the patch. The simulated result shows it provides the return loss less than -10 dB for two frequencies 1.27 GHz and 1.43 GHz which could be a useful frequencies for wireless communi-cation system. The simulation work is carried out on IE3D software, a product of Zeland Software Company.
