A Wideband Microstrip-Fed Monopole Antenna for WIBRO, WLAN, DMB and UWB Applications

A small wideband microstrip-fed monopole antenna which consists of a radiating patch with two L-shaped notches and stubs at the lower corners and truncated ground plane, is presented for various mobile communication services such as WiBro, WLAN, DMB, and UWB applications. The proposed antenna is designed to operate over 2.3 to 10.7 GHz for S 11 < −10 dB. In this paper, numerical analysis using Ansoft HFSS and details of the proposed antenna design approach and measured results are also presented and discussed.
