The term ultrawideband (UWB) in antenna research has become a buzzword over the past decade. In recent years, advancement in this new area has given birth to numerous antenna designs. A simple and practical method to design an ultra-wideband microstrip antenna is presented. The overall dimension of the proposed ultra-wideband antenna is (20 x 20) mm(2) and it consists of a defected ground along with the two layers stacking. The proposed is operating between 11.97 and 20.54 GHz which covers both downlink and uplink frequencies of Ku band and partially K band (2.54 GHz).The modeling and simulation is performed using Ansoft HFSS (High Frequency Structural Simulator) software. This proposed prototype achieves the peak gain of 8.5 dBi and maximum radiation efficiency of 88.5%.
