Abstract

This paper describes the comparision of a microstrip-fed monopole ultra wideband antenna with and without notch. In case of notch the notch-band characteristics is achieved by C- shaped ring resonator. The paper gives better understanding of antenna parameters such as return loss, VSWR etc., and its variation in performance of antennawith and without notch. Also presents the effect of parameters of antenna with notch on gain. Finally, simulation is done using Ansoft HFSS software. Measurements indicate that antenna operates in the band from 2.25 -10.2GHz and has band-rejected characteristics in 5.16-5.85GHz which covers wireless Local Area Network band.
