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 semicircular 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 2.71 GHz to 16 GHz for VSWR 2:1. A semicircular slot is embedded in a planar inverted cone for rejecting the 5 - 6 GHz WLAN band. Prototypes are fabricated according to the optimized parameter values, and the antenna characteristics are measured. The results show that the proposed antennas are of the UWB characteristics and exhibit band rejection of 5 - 6GHz. The radiation patterns are stable and omnidirectional.
