Abstract

This paper presents a new design of 5.5 GHz band-notched slot antenna fed by a Coplanar Waveguide (CPW) for Ultra-Wideband (UWB) application. By converting a square radiating stub to the stepped structure, a good impedance bandwidth can be achieved, which covers an UWB frequency range. The bandnotched characteristic of this antenna is realized by adding an inverted U-shaped parasitic strip on the other side of antenna substrate. The proposed antenna can operate from 2.85 to 11.93 GHz with a rejection band around 5.02 to 6.13 GHz, to avoid any interference form the Wireless Local Area Network (WLAN) systems. The proposed antenna displays good omni-directional radiation patterns. Simulated and measured results are presented to validate the usefulness of the proposed antenna structure for UWB applications. The designed antenna has a small dimension of 30×30×0.8 mm3 .
