A Modified E-Shaped Microstrip Antenna for Ultra Wideband Wireless Systems

In this paper, the analysis of a modified E-shaped patch antenna is presented. The purpose of the modification over the original E-shaped structure is to accommodate the operating frequency band and signal bandwidth requirements of the Ultra Wideband (UWB) wireless system. Simulation results show that the modified R-shaped has fulfill the frequency band and signal bandwidth requirements of the UWB system. A resonance frequency of 3.5 GHz and signal bandwidth of 29.3% is achieved for the presented structure. The analysis of the proposed antenna has been done using the finite difference time domain (FDTD) with Perfect Matched layer (PML) approach. Results have been compared with published data and good agreements are found.
