A tapered microstrip-fed printed inverted cone antenna with band-notched characteristics suitable for Ultra-WideBand (UWB) wireless systems is proposed. The antenna design consists of a semi-circular slot embedded in a planar inverted cone as the radiating patch and a partial tapered ground plane. The proposed antennas are printed on a substrate of permittivity 4.4 and operate over a wide impedance bandwidth from 2.71GHz to 16GHz for VSWR 2:1. A semicircular slot is embedded in a planar inverted cone for rejecting the 5-6GHz WLAN band.
