A coplanar strip fed enhanced gain directional radiator with a V shaped slot suitable for FCC specified ultra wide band application is developed. The 2:1 VSWR bandwidth of the antenna is nearly 9GHz ranging from 3.1 to 12 GHz. Proposed structure possess average radiation efficiency greater than 90% and a larger gain of 5 dBi in the entire range of frequencies of operation. Radiation patterns and polarization characteristics of the antenna are also uniform in entire band. Measured group delay of the structure is very minute and thus antenna has an excellent time domain performance. Transmitted and received pulses by the antenna are almost similar and thus the dispersion will be minimum.
