    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.

    The coplanar waveguide fed slot antenna with inset U-strip tuning stub is proposed for wideband applications. The antenna consists of rectangular slots with conductor tuning stub fed by CPW feed line. This antenna is design for match impedance with 50 ohm of characteristic impedance of transmission line. By adjusting dimension of inset U-strip tuning stub, the range of bandwidth can be achieved from 1.66 GHz to 7.22 GHz which can operate in WLAN (Wireless Local Area Network) according to IEEE 802.11 a/b/g standards and covered the WiMAX (Worldwide Interoperability for Microwave Access, IEEE 802.16e) and can operate for mobile GSM1800, GSM 1900. The characteristics of antenna are proposed and analyzed for instance input impedance, return loss, bandwidth, VSWR, and far field radiation patterns.
