Abstract

The effects of parasitic dielectric resonators on the HE_11δ and HE_13δ modes of a cylindrical dielectric resonator antenna (DRA) have been studied. The DRA was excited electromagnetically with a grounded coplanar waveguide through an aperture in the common ground plane. Strong couplings were observed for the HE_11δ mode with the parasitic element superimposed on the driven DRA, and for the HE_13δ mode with parasitic elements placed on both sides of the driven DRA. Results indicate significant enhancement in bandwidth for both modes, and good radiation patterns for the HE_11δ mode.
