A highly compact dual-band WLAN/UWB monopole antenna

A highly compact microstrip-fed planar monopole antenna is proposed. It consists of a radiation patch, four stubs and a truncated ground. The antenna exhibits dual-band operation with -10dB return loss bandwidths 0.45GHz (2.20-2.65GHz) and 5.23GHz (6.52-11.75GHz) in the lower band and upper band, respectively. Simulated and measured results show this antenna is suitable for WLAN, UWB and other wireless communication applications.
