A dielectric resonator antenna system is disclosed wherein a dielectric material having a high dielectric constant is placed between a dielectric resonator antenna (DRA) and the antenna feed. Preferably the dielectric material having a high dielectric constant is either in the form of an insert within a cavity of the DRA or alternatively is in the form of a thin layer between the feed and the DRA for enhancing coupling therebetween. It is preferred that the high dielectric constant material be at least twice the value of the dielectric resonator antenna.

A radiating antenna capable of generating or receiving circularly polarized radiation is disclosed using a single feed and a dielectric resonator. The dielectric resonator has slightly differing dimensions along two axes. Substantially polarized radiation can be generated in each of two mutually orthogonal modes by placement of the probe at each of two locations. When the feed is situated substantially between these two locations, two orthogonal modes are excited simultaneously.
