Design of Square Microstrip Antenna Using T-Shaped Notch in the Ground Plane for Ultra Wideband Applications

This paper presents the design of an ultra wideband microstrip patch antenna for (UWB) communications. In this structure there is a square patch consists of a partial ground plane and fed by a 50 ? microstrip line. The proposed antenna can achieves a wide bandwidth from 1.52 GHz to 11.19 GHz with VSWR<2 with stable and bi-directional radiation pattern. The simulation of this antenna has been performed by using Ansoft High Frequency Structure Simulator (HFSS) and Computer Simulation Technology-Microwave Studio (CST).
