In this paper, we present an offset microstrip-fed ultrawideband antenna with band notch characteristics.The antenna structure consists of rectangular radiating patch and ground plane with rectangular shaped slot, which increases impedance bandwidth upto 117.73%(2.9-11.2GHz).A new modified U slot is etched in the radiating patch to create band-notched properties in the WiMAX (3.3- 3.7GHz) and C-band satellite communication (3.7-4.15GHz).Furthermore, parametric studies have been conducted using EM simulation software CADFEKO suite(7.0) and optimized with stable radiation pattern which satisfied UWB requirement for VSWR |
