UWB Monopole Antenna with Triple-Band Notch Rejection

Abstract

A compact monopole with multiple band notches filtering antenna is analyzed in this paper. The monopole antenna includes a rectangular patch which covers the ultra-wideband (UWB) frequency range from 3.1GHz to 10.6GHz. Further to reject the interfering licensed frequency bands like WiMAX, wireless local area network (WLAN) and X-Band, λg/2 resonators are used. The rectangular split ring resonator within monopole radiator is used to create band notch at 3.5GHz (WiMAX) and E shaped dual notch resonator for notch bands at 5.8GHz (WLAN) and 8.4GHz (X-Band). The proposed prototype is designed and simulated in commercially available software known as CST Microwave Studio. Simulated results are showing the performance of proposed filtering antenna as desired.
