Bifrequency behaviour and bandwidth enhancement of a dielectric resonator antenna

In this paper, we present a new configuration which enhances the impedance bandwidth (we obtain an increase of 80%) and exhibits dual-frequency operation. The characteristics of the new structure are measured and discussed. © 2004 Wiley Periodicals, Inc.
