Abstract

In this paper, numerical investigation of band rejection capabilities of UWB elliptical slot antenna with circular and crescent shaped radiators are presented. The band rejection performance can be achieved either by a C-shaped slot in the ground plane design A or by cutting a C-shaped slot in the microstrip feedline design B. The calculated VSWR of the both antenna designs show an impedance bandwidth starts from 2.5 GHz to beyond 14 GHz for VSWR<;2 except in the 5.0 - 6.0 GHz frequency range. Also, both designs show relatively stable radiation patterns over the whole UWB frequency band and are considered good candidates for UWB applications.
