FLAT LENS MATCHING METHOD Russian patent published in 2021 - IPC H01Q19/06 H01Q15/08 

FIELD: communication.

SUBSTANCE: invention can be used to create antennas for communication and near location. In the method, the radial gradient of the effective dielectric constant is formed by through perforating a certain number of holes in the lens material, matching layers are formed on both sides of the plate by non-through perforation. The effective dielectric constant of the main ε_n and matching layers at a distance ρ_n from the center of the lens, the depth of non-through perforation in the matching layers and the proportion of the areas occupied by the holes in the cross-sections of the main w_n and matching ν_n layers are determined from the ratios given in the set of claims.

EFFECT: simultaneous fulfillment of the conditions of focusing to infinity and lens matching.
