A compact planar ultrawideband (UWB) antenna with 5/6 GHz band-notched characteristics has proposed. The proposed antenna is a uniplanar structure and has a compact area of 25Ã25 mm2, which covers the frequency band from 3.1 to 10.6 GHz (VSWR Â¿ 2). The antenna consists of a circular ground plane and a circular metal patch is printed within that. A 50-Â¿Â¿ coplanar waveguide (CPW) transmission line is used to feed the printed circular metal patch. By removing a C-shaped slot from the circular patch, band rejected property in the WLAN band is obtained. The proposed antenna is simulated and designed showing broadband impedance matching, consistent radiation pattern and stable gain.
