Abstract

A Compact coplanar waveguide (CPW) fed ultrawideband (UWB) antenna is presented. The antenna consists of a corrugated half circular disc radiator and a notched CPW ground plane which are used to improve the impedance bandwidth and also to reduce the overall size to only 0.22 × 0.22 λ² at 3GHz. The calculated impedance bandwidth of the proposed antenna ranges from 3.5GHz to 11GHz for a reflection coefficient (S₁₁) less than -10dB. The proposed antenna has a relatively stable radiation patterns over its whole frequency band of interest. A U-shaped slot is embedded to obtain the band-notched characteristic in the 5.0-6.0 GHz wireless local area network (WLAN) band.
