Abstract

A narrow slot coupled to a microstrip line excites a dielectric resonator antenna (DRA) consisting of a small dielectric disc embedded in a larger disc is built and tested. Two different configurations of DRAs are tested with two different slots providing eight different possibilities. One configuration provides a bandwidth over 50%. These antennas have broadside radiation patterns because of the symmetry presence of the slot with the DRA. Sample of radiation patterns are provided.
