    An ultra-wideband rectangular ring antenna led by stepped monopole is presented in this paper. The initial parameters of antenna design as well as the antenna revolutions for enhancing impedance bandwidth are shown. Simulations have been carried out to investigate the impedance and radiation behaviors. It is found that the antenna offers a bidirectional radiation pattern with the impedance bandwidth covered the frequency range from 3.1-10.6 GHz with the VSWR of less than 2:1.

    A wideband rectangular ring antenna fed by planar disc monopole is presented. The antenna radiates bidirectional beam with average directivity of 6 dBi. The antenna characteristics are simulated and analyzed. Experiments have been carried out to investigate the impedance and radiation behavior and the results are compared with the simulated data. The antenna offers a wide impedance bandwith in the frequency band 2.2-16.7 GHz with the VSWR of less than 2:1. Copyright 2006 IEICE.
