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.
