Abstract :
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.
