Summary:A novel microstrip slot antenna for UWB (Ultra Wideband) applications is proposed. A square ring slot antenna is filledb y an H shape slot as a parasitic element. This structure is fed by a single microstrip line with a fork like-tuning stub. Experiments are carriedout to investigate its return loss, its radiation andits time domain behavior, which exhibit good radiation pattern and impedance bandwidth over the entire band of frequency. Time domain consideration also exhibits that this antenna can be used with short pulses. Extended from the proposed antenna, one advanced bandnotched( 5.5-7 GHz) design is also presentedas a desirable feature for UWB applications.
