Abstract
The circular disc monopole (CDM) antenna has been reported to yield wi de-impedance bandwidth, Experiments have been carried out on a CDM tha t has twice the diameter of the reported disc with similar results. Ne w configurations are proposed such as elliptical (with different ellip ticity ratios), square, rectangular, and hexagonal disc monopole anten nas. A simple formula is proposed to predict the frequency correspondi ng to the lower edge of the bandwidth for each of these configurations , The elliptical disc monopole (EDM) with ellipticity ratio of 1.1 yie lds the maximum bandwidth from 1.21 GHz to more than 13 GHz for voltag e standing wave ratio (VSWR) < 2.
