STEERABLE-BEAM MULTIPLE-FEED DIELECTRIC RESONATOR ANTENNA OFVARIOUS CROSS-SECTIONS

摘要

A radiating antenna capable of generating or receiving radiation using a plurality of feeds and a dielectric resonator of various cross-sections is disclosed. The purpose of using multiple feeds with a single dielectric resonator antenna is to produce several beams each having a "boresight" in a different direction. Several such beams may be excited simultaneously to for m a new beam in any arbitrary direction. The new beam may be incrementally or continuously steerable and may be steered through a complete 360 degree circle. The invention may be combined with an internal or external monopole antenna so as to cancel out the antenna backlobe or otherwise resolve the front/back ambiguity that arises with this type of dielectric resonance antenna.
