New wideband monopole antennas

Abstract

Several new wideband configurations, such as, elliptical, square, rectangular, and hexagonal disc monopole antennas have been fabricated and results have been compared with the reported circular disc monopole antenna. The elliptical disc with ellipticity ratio of 1.1 yields the largest bandwidth from 1.21 GHz, to more than 13 GRz for VSWR < 2
