Abstract

A bidirectional cylindrical dielectric resonator antenna (DRA) is proposed in this paper. The DRA operating in its fundamental TM01δ mode is fed by an axial coaxial probe protruded from a circular ground, which has the same radius of the DRA. Two slots are fabricated on the ground to obtain a bidirectional radiation pattern. It was found that the measured gain on the azimuth plane is 3.75 dBi and −10.16 dBi in the mainlobe and sidelobe directions, respectively.
