Abstract
The coplanar waveguide fed slot antenna with inset L-stripe tuning stub is proposed for UWB applications. The antenna consists of two rectangular slots separated by center strip with CPW feed line. This antenna is design for match impedance with 50 ohm of characteristic impedance of transmission line by using inset L-stripe tuning stub for wideband matching. By adjusting dimension of inset L-strip tuning stub, the range of bandwidth can be achieved 144.6% (1.80 GHz -11.2 GHz) of the center band coverage standard of IEEE 802.15a for ultra wideband operation. The characteristics of antenna are proposed and analyzed for instance input impedance, return loss, bandwidth, VSWR, and far field radiation patterns. © 2008 SICE.
