    A compact ultra-wideband (UWB) CPW-fed slot antenna design is presented. The antenna consists of a wide rectangular slot on the ground plane with rectangular-ring shaped tuning stub. The simulation result of the impedance matching for the proposed antenna show the impedance bandwidth, determined by-10 dB return loss of 116 %, coverage 2.94 GHz to 11.06 GHz for UWB applications. The simulation radiation patterns and gain of the antenna at different operational frequencies are presented and discussed.

    This paper presents the slot antenna fed by coplanar waveguide (CPW) for WLAN applications. The characteristics of an antenna are proposed and analyzed for instance return loss, bandwidth and far field radiation patterns. Simulation results of the proposed antenna show the impedance bandwidth, determined by-10 dB return loss, approximate 140 % (1.66-9.44GHz) of the center band. The radiation patterns are bi-directional, and maximum gain is 5.7 dBi at 5.0 GHz. The simulation results of the slot antenna are analyzed by using IE3D Software.
