3.5/5.5 GHz dual band-notch ultra-wideband antenna
A compact and simple design of a CPW-fed planar antenna for ultra-wideband application with dual band-notch characteristics is presented. The proposed antenna yields an impedance bandwidth of 3.1–10.6 GHz with VSWR<2, except the bandwidths of 3.3–3.9 GHz for WiMAX and 5–6 GHz for WLAN. The antenna is successfully simulated, designed, and measured, showing broadband matched impedance, stable gain and omnidirectional radiation patterns.
