Abstract: A new compact band-notched S-shaped Dielectric Resonator Antenna (DRA) for ultra wideband (UWB) applications is presented. An excellent notch band characteristic is achieved by implanting an inverted T-shaped parasitic strip on the front plane of dielectric substrate. By etching a rectangular slot on the ground plane, the width of the notch band characteristics can be controlled. The overall size of the antenna is 11?23?0.75mm?.The results obtained by measurement depict that the presented DRA achieves satisfactory radiation characteristics along with UWB impedance bandwidth of around 135% with a sufficient band rejection in the band of 5.15-5.825GHz, high radiation efficiency and nearly constant gain.
