This paper introduces a novel E-shape microstrip patch antenna for multi-band and multi-polarization facility using single layer structure. This E-shape antenna operates at three sub-bands, namely 5.75, 13.5 and 19.4 GHz with 20%, 70%, and 10% bandwidths respectively. By using only single patch a high impedance bandwidth is achieved. The proposed antenna has simple structure consisting E-shape on a rectangular patch dimension of the antenna come around 35mm×30mm×1.25mm and fed by 50 probe feed. The impedance matching and radiation characteristics of the designed structure are investigated by using MOM based IE3D. It has two ports excited with microstrip line feed mechanism. The simulation results show that the antenna offers excellent performance for UWB application ranging (5.35GHz to 6.52GHz) and (8.42GHz to 17.4) and (18.5GHz to 20.65GHz) simultaneously.
