    Abstract

    An extremely compact ultrawideband (UWB) dielectric resonator antenna is presented for potential use in compact UWB wireless communication devices. The antenna consists of a dielectric resonator of relatively high permitted attached to a thin dielectric segment of relatively low permittivity, positioned on a ground plane. The current version is fed by a coaxial probe although other feeding methods are possible. The use of two dielectrics and multiple resonance modes have helped this design to cover the entire FCC UWB band (3.1 - 10.6 GHz, 1:3.4 or 109.5% bandwidth) in a very small volume. The antenna size has been further reduced, without compromising the bandwidth, by removing about half of the dielectric volume and applying a metal coating on one side of the dielectrics.
