Design of rectangular U-shaped fork patch antenna for UWB and multiband applications

Abstract

A compact, simple and elfin printed unequal legs of rectangular U shaped fork patch antenna is proposed for Ultra Wideband (UWB) and Multiband applications. Ultra wide band operation covers 3.1–10.6 GHz (UWB) frequency band and also enhanced bands which are extremely wider than UWB are obtained by using unequal legs of rectangular U shaped fork radiating patch and a modified ground plane. The proposed antenna gives the Omni-directional radiation pattern and acceptable gain over UWB and multiple enhanced frequency bands. The proposed antenna is tested and fabricated.
