Abstract

This letter proposes a planar modified circular ring antenna for ultrawideband (UWB) applications with band notch performance. By suitably adjusting the antenna parameters, a return loss of 10 dB is achieved over the desired frequency range (3.110.6 GHz) except the notch frequency band. The band-notched characteristic is achieved by introducing a tuning stub inside the ring monopole. The results for return loss and radiation pattern are simulated using electromagnetic simulator WIPL-D. The time domain behavior of the antenna in terms of the fidelity factor is evaluated using Computer Simulation Software (CST) transient solver. A prototype antenna is fabricated, and the simulated result for return loss is compared to the measured result.
