A novel ultra-wideband (UWB) antenna with the 3.4/5.5 GHz dual band-notched characteristics is proposed.The antenna consists of a clevis-shaped radiating patch and a coplanar waveguide (CPW) transmission line.It yields an impedance bandwidth of 3.1~10.6 GHz with return loss S11<-10 dB,except for the two subbands of 3.3~3.7 GHz for WiMAX and 5.15~5.825 GHz for WLAN.These notched subbands are obtained by etching two slits and a U-shaped slot on the radiating patch.The antenna was successfully fabricated and measured,showing broadband matched impedance and a nearly omnidirectional radiation pattern.
