Abstract
A simple and compact circular ultra-wideband (UWB) planar monopole antenna with dual band-notched characteristics is presented. By inserting a pair of two slots in the ground plane as well as adding a pair of arc-shaped parasitic strips around the radiating element, two notched frequency bands in the WiMAX/WLAN are achieved. Experimental results show a VSWR<2 bandwidth of 7.6 GHz for nondefected antenna and two highly rejected bands in the frequency region of 3.3–3.7GHz and 5–6GHz. © 2012 Wiley Periodicals, Inc.
