A small size elliptically tapered slot antenna (ETSA) fed by coplanar waveguide (CPW) for ultra-wideband (UWB) applications is proposed. It is printed on an FR4 substrate and occupies a size of 37×34×0.8 mm. A pair of quarter circular shapes is etched on the radiator to reduce the size. To overcome the limitation of uniform corrugation, non-uniform corrugation is utilized to reduce the cross-po...

Abstract—A novel compact open-ended L-shaped slot antenna with asymmetrical rectangular patch is demonstrated and designed for UWB applications. With the open-ended L-shaped slot and an asymmetrical rectangular patch fed by the micro-strip line, multiple resonant frequencies are excited and merged to form a measured widen operating bandwidth of 3.01 ∼ 11.30GHz with 10 dB return loss. The fracti...

In this paper, a compact ultra wideband (UWB) monopole antenna with a band-notched characteristic is presented. The bandnotched characteristic is achieved by inserting a U-shaped slot in the half elliptical ring radiating patch. The measured bandwidth of the designed antenna for |S11| 6 −10 dB spans 3.1 GHz to 9.3 GHz with a notched band (|S11| > −10 dB) spanning 5.12GHz to 5.99 GHz. A quasi-om...
