Printed Annular Ring Monopole Antenna for UWB Application

This paper proposes a novel printed annular ring monopole antenna for UWB application. The proposed antenna effectively covers the 3.1 to 10.6 GHz UWB frequency band, which has been approved by the Federal Communications Commission as a commercial UWB band. Prototype of the proposed antenna is designed, fabricated and tested using feed through straight SMA connector. The proposed antenna has a VSWR < 2 over the UWB frequency band. The measured VSWR and radiation patterns indicate the suitability of this antenna for UWB applications.
