Abstract

Abstract. Results of theoretical and experimental investigation of a novel dual frequency coaxial-horn conical horn antenna have been presented. Main part. The antenna design merges two concepts, namely: a dielectric rod, which is a prolongation of the internal waveguide within the coaxial structure; and a partially filled co-axial horn antenna. The former provides operation in the upper frequency band whilst the latter delivers lower frequency band operation. The proposed modified horn antenna, similar-ly to its prototypes [1, 4], possesses an axial-symmetrical radiation pattern and low level of cross polarisation in both wide operational frequency bands. However, unlike the prototype antennas, the novel structure provides better symmetry of radiation pattern in principal planes and lower level of side-lobes. Conclusion. A novel concept of dual band feed system with partial dielectric loaded have been discussed.
