Design of Ultra Wideband Patch Antenna

Abstract

This paper presents an ultra wideband(UWB) antenna which is in rectangular shape is designed and analyzed by Microwave Studio Computer Simulation Technology(MS CST).The antenna uses FR-4 substrate. The rectangular patch which is excited by micro strip line is printed on the top of the substrate and a partial ground plane is printed on the other side. The basic structure of antenna produces ultra-wideband characteristics. But these characteristics can further be improved by cutting the lower left corner of the patch as stair case and observed the simulated results like return loss(S11), voltage standing wave ratio(VSWR), gain and bandwidth(BW).
