ANTENNA ARRAY WITH A SEMI-TRANSPARENT DEPOLARIZING METASURFACE Russian patent published in 2023 - IPC H01Q1/00 H01Q21/29 

FIELD: radio engineering.

SUBSTANCE: wide-angle scanning antenna array. The antenna array contains a plurality of antenna array elements, and above the antenna array there is a metasurface, which is a dielectric layer, on one side of which there are conductive elements configured to reflect part of the radiation of the antenna array, and the distance between the antenna array and the metasurface is h ≈ 0.5λ(1 + n) / cos(θ_S), where n is an integer number of half-waves (n=0, 1, 2...), λ is the operating wavelength of the antenna array in the medium in the gap between the antenna array and the metasurface, and θ_S is the predetermined scanning angle of the antenna array.

EFFECT: expanding the scanning range, increasing the efficiency of the antenna array and reducing losses.
