ABSTRACT:
An artificial dielectric antenna structure for reducing the mass and insertion loss of an antenna is provided. The artificial dielectric antenna structure includes a plurality of layers of dielectric material. Each layer of dielectric material has a dielectric constant. The artificial dielectric antenna structure further includes a plurality of spacing layers interposed between the plurality of layers of dielectric material. Each of the plurality of spacing layers has a dielectric constant lower than the dielectric constant of any of the plurality of layers of dielectric material. The artificial dielectric antenna structure may be disposed within a horn antenna. The artificial dielectric antenna structure may alternately be disposed upon a transmission medium to form a dielectric resonator antenna.
