ABSTRACT:
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.
