Radiation characteristics of a short dielectric rod antenna excited by a circular waveguide is investigated experimentally. It is found that, by a proper selection of the waveguide radius and the exposed length of dielectric rod, the E and H plane radiation patterns, the side and back radiations and the bandwidth of the antenna can be controlled. Some experimental data are presented and the usefulness of this antenna as a feed for paraboloidal reflectors is also discussed.

The similarity of a horn with corrugated flange and a horn with dielectric coated flange is discussed. Radiation characteristics of a circular horn with dielectric coated flange excited by a circular guide is then investigated experimentally. It is found that by a proper selection of the various elements-the waveguide radius, the distance from the waveguide aperture to the dielectric surface, the airgap thickness and the size of the flange-the E and H plane radiation patterns, the side and back lobe radiations and the bandwidth of the antenna can be controlled. These characteristics are found to be very similar to those obtained from a circular horn with corrugated flange. Some experimental data is given, as well as discussion of the usefulness of this antenna as a feed for paraboloidal reflectors.
