- 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<2.A prototype of antenna is fabricated on 1.6mm thick FR-4 substrate with dielectric constant of 4.4 and loss tangent of 0.02.The designed antenna exhibits bidirectional and omni directional radiation patterns along E and H-plane with stable gain and efficiency over entire operating band except notch frequency band. Simulated results are in good agreement with the measured results of the proposed antenna which makes it a good candidate for UWB application.
