    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.
