Abstract :
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.
