In this paper, a design of co-axial feed circularly polarized rectangular microstrip patch antenna with 'O' slot for UWB application. Here, microstrip patch antenna is designed to improve the efficiency as well as bandwidth. The microstrip patch antenna is very popular for its low profile, low cost, light weight, easy to feed and their attractive application. The return loss is below -25dB from 2GHz to 4GHz. A maximum gain achieved at 3.5GHz frequency. The VSWR is less than 2.
