A Compact Monopole Antenna for Wireless Applications

A tiny wideband microstrip-fed monopole antenna which includes of a radiating patch with two L-shaped notches and stubs at the lower corners and truncated ground plane, is suggested for various mobile communication services such as WiBro, WLAN, DMB, and UWB applications. This antenna which is presented here is designed to function over 2.3 to 10.7 GHz for S11 < -10dB. In this paper, numerical analysis using Ansoft HFSS and details of the proposed antenna design approach and measured results are also presented and discussed.
