Abstract |
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 E-shaped has fulfilled the frequency band and signal bandwidth requirements of the UWB system. A resonance frequency of 3.5 GHz and signal bandwidth of 29.3 percent is achieved for the presented structure. The radiation pattern for these antennas is almost omnidirectional. For the applications of ISM (industrial, scientific, and medical) band where directive antennas are needed, multi-reflectors are used with the E-shaped antenna. The analysis of the proposed antenna has been done using the Finite Difference Time Domain (FDTD) with Perfect Matched layer (PML) approach in addition to numerical package based on the method of moment (MOM). Results have been compared with published data and good agreements are found. |
