Abstract :
A novel circular wire antenna suitable for ultra wideband (UWB) applications is presented in this paper. It consists of a circularly curved wire over a ground plane. The wire structure is designed to deliver approximately the same benefits as a circular disc antenna. Effective length is introduced to analyze the operation of the antenna. Experimental results of the antenna have demonstrated the antenna achieves an impedance bandwidth from 3.1 to 10.6 GHz with a return loss of less than -6 dB. This antenna provides omm-directional radiation patterns consistently over the operating frequencies. Further more, transient response of the antenna is measured to validate the suitability for UWB communication.
