Modern and future wireless systems are placing greater demands on antenna designs. This paper describes design of circular disk monopole antenna for operating frequency 3.0GHz-20.0GHz. This proposed antenna giving superior performance over conventional antennas with high gain 17dB, high directivity and symmetrical E-plane and H-plane characteristics which make this antenna suitable for Ultra-Wide Band (UWB) and broad band applications. This paper presents the return loss, input impedance, radiation patterns, VSWR, e-field, H-field and current distributions using CST software.
