Dielectric resonator antenna with mutually orthogonal feeds
First Claim
1. A dielectric resonator antenna including a grounded substrate, a dielectric resonator contacting or in close proximity to the grounded substrate, and three feeds for transferring energy into and from different regions of the dielectric resonator, characterized in that the dielectric resonator is formed as a volume having three mutually orthogonal surface planes of substantially the same size and shape, and in that the feeds contact the dielectric resonator at substantially central portions of the three surface planes such that the feeds are also mutually orthogonal.

Abstract
A multi-polarisation dielectric resonator antenna (1) having three mutually orthogonal feeds (5a, 5b, 5c) displaying C3V point group symmetry is disclosed. The antenna (1) may be operated so as to determine the polarisation of any incoming signal, since the three feeds (5a, 5b, 5c) have polarisations at 120 degrees to each other. Furthermore, a plurality of mult dielectric resonator antennas (1) may be formed into a composite dielectric resonator antenna with beamsteering, direction feeding and polarisation detection capability over a full 4π streradians.
