UWB Antenna Design with Required Band Suppression Characteristics For Cognitive Radio Applications

Abstract

This paper presents the design of ultra wideband monopole antenna that  can resonate over a range of frequencies from 2GHz to 10GHz which is appropriate for cognitive radio applications.  The antenna is equipped with Split Ring Resonators which can notch two narrow band frequencies 4.47GHz to 4.82GHz, 6.94GHz to 7.77GHz and wide band greater than 8.41GHz. The design is simulated and the results are obtained using HFSS electromagnetic simulation software.
