Abstract

This paper presents a compact and low-profile printed antenna that exhibits adequate performance for UWB communications. The antenna is based on a combination of two crossed exponentially tapered slots plus a star-shaped slot to produce a completely symmetric balanced structure. The radiation pattern presents smooth frequency dependence and very stable polarization over the 3.1-10.6 GHz FCC assigned band. Results are confirmed with measurements. Figures of merit like output pulse fidelity and time window containing 90% of the transmitted energy are analyzed and showed to comply with UWB application requirements.
