Since the Federal Communication Commission (FCC) released the bandwidth of 3.1 to 10.6GHz for the unlicensed use of the Ultra-WideBand (UWB) in February 2002, UWB technology has become the most promising candidate for wireless communications. The demand for UWB antenna is also increasing. This paper presents a tapered microstrip-fed asymmetric Planar Inverted Cone Ring Antenna (PICRA) for Ultra-WideBand (UWB) applications. The proposed antenna design is comprised of an asymmetric inverted cone ring as the radiating patch, a tapered microstrip-fed line and modified tapered ground plane.
