Abstract. The influence of anisotropy of the average permittivity of a perforated structure in the form of a hexagonal lattice of round holes in a solid dielectric on the characteristics of an antenna based on a cylindrical perforated Mikaelyan lens was studied for different lens synthesis options. It was shown that phase aberrations in the lens aperture are minimal when synthesized according to the requirement of precise focusing of «ordinary» rays. The characteristics of an antenna based on a perforated Mikaelyan lens synthesized in this way were investigated. It was shown that anisotropy limits the maximum values of the antenna directivity, and the greater the permittivity of the material, the more strongly.

Key words: lens antenna, Mikaelyan lens, perforated dielectric, anisotropy.

Financing: The work was carried out using budget funding within the framework of the state task 0030-2019-006.
