Abstract
This paper describes some results of an extensive theoretical and experimental work on a novel type of antenna design-a ring-shaped dielectric antenna. It consists of two basic elements:a dielectric ring and a primary feed. One possible construction of a such antenna has a ring with rectangular cross-section and a waveguide-dielectric radiator serves as a primary source. The optimum dielectric ring for a maximum antenna gain gets into the second Fresnel zone. A radiation theory and experimental results for an X-band antenna model are given in the paper. It is concluded that a ring shaped dielectric antenna is an efficient directional radiator with simple and cheap construction.
