Design and Analysis of a Compact Rectangular Sectored UWB (Ultra-wideband) Antenna for Wireless Communication Applications

A compact rectangular sectored monopole ultra wide band (UWB) antenna is represented for WLAN and WiMAX applications. This article shows UWB characteristics with a wide operating bandwidth (1.5GHz - 9GHz) of 7.5GHz. It also shows the stop band filtering characteristics from 2.89GHz to 3.65GHz, which will be used to filter out the ISM band (2.4GHz), mobile communication (4.4GHz) and wireless data transfer (7.2GHz) signals. All the antenna characteristics parameter like gain, return loss, radiation pattern has been studied experimentally and verified it. From the simulated result it shows a good agreement.
