An efficient, low cost Parallel metal plated split U-shape Omnidirectional UWB Antenna structure with 1x3 microstrip line feed is proposed. The antenna structure having 0.6mm thick foam dielectric placed between ground plane and radiating structure. The Antenna structure is designed for predetermined frequency band.  The proposed antenna offers high efficiency, stable gain, small group delay variation and its radiation patterns indicate its suitability for UWB applications.
