In the proposed paper, a planar monopole antenna with modified patch and truncated ground plane for Ultra wideband (UWB) applications is presented. The radiating element of the proposed antenna is fed by a 50 Ω microstrip line. Truncation in the ground plane is made for better impedance matching. It is found that by making steps in the ground plane, return loss characteristics and hence the VSWR is improved. The antenna parameters and performances have been investigated by using commercially available CST Microwave Studio software. Simulation and measurement results show that the proposed antenna provides an ultra wide bandwidth, completely covering the range set by the Federal Communication Commision (FCC) for UWB operations (3.1 GHz to 10.6 GHz).The antenna is of low profile and exhibits omnidirectional radiation pattern and high gain for the entire bandwidth.
