Abstract
Higher order HEM 12δ mode in Cylindrical Dielectric Resonator Antenna (CDRA) has been introduced recently by the present authors with the aim to achieve broadband high gain radiation along with its conventional broadside radiating HEM 11δ mode. Two different techniques have been proposed and demonstrated so far. In this paper, yet another method is proposed, which is the simplest one compared to the earlier ones. Proposed technique uses unusually long vertical probe, placed in touch with the surface of a CDRA, both sharing the same ground plane. Simulated results promise for remarkably satisfactory performance of the CDRA showing high gain broadside radiations caused by both HEM 12δ and HEM 11δ modes. Fabrication and measurements are under progress. Those results will be provided later.
