Dual Band – Notch Elliptic Shaped Monopole UWB Filtering Antenna

Abstract

In this paper a compact elliptical monopole UWB Antenna is analyzed. Proposed structure covers the frequency band of UWB spectrum defines from 3.1 to 10.6 GHz. Symmetrical and Monopole structure of this proposed UWB Antenna is helping to achieve the good matching of impedance. Although multiple interfering frequency bands are existing in the define UWB spectrum. Filtering characteristics have been incorporated to eliminate the effect of existing interfering bands. Two λg/ 2 rectangular split ring resonators (R-SRR) are used within the monopole radiator. These R-SRR are producing notch in WiMAX and X-Band of UWB spectrum. Commercially available software CST Microwave Studio has been used for design and simulation of proposed prototype. Results achieved from the simulation are showing the desired performance characteristics of proposed prototype. Return loss of the proposed UWB Antenna is better than −10 dB and gain and efficiencies are in good agreement as desired.
