Compact CPW-fed ultra-wideband antenna with dual band-notched characteristics
A coplanar-waveguide (CPW)-fed ultra-wideband antenna with dual band-notch characteristic is presented. The antenna is as small as 21×28×1.6 mm3. The proposed antenna yields an impedance bandwidth of 3.1–10.6 GHz with VSWR<2, except for the bandwidth of 5–6 GHz for WLAN and 7.7–8.5 GHz for X-band. The antenna has been successfully simulated, fabricated and measured, showing good impedance matching, stable gain and near omnidirectional radiation pattern.
