A novel compact ultra-wideband printed dipole antenna with tapered slot feed

Ultra wide band (UWB) techniques draw more and more attention in recent years. Nevertheless, it is not easy to find a proper antenna for such systems. In this paper, we propose a novel compact antenna suitable for ultra-wideband applications. This new antenna is characterized by its ultra-wideband quasi-omnidirectional patterns in the H-plane. Measurement results demonstrate a 4:1 bandwidth for both input return loss as well as H-plane patterns.
