## Abstract

The disclosure relates to radio engineering, and more specifically, to a wide scan angle antenna array. Technical result consists in expanding the scanning range, increasing the efficiency of the antenna array and reducing losses. Antenna array is provided. The antenna array includes a plurality of antenna array elements, and a metasurface disposed above the antenna array, wherein the metasurface is a dielectric layer having, on a first side thereof, conductive elements configured to reflect part of radiation of the antenna array; the distance between the antenna array and the metasurface is based on an integer number of half wavelengths, an operating wavelength of the antenna array in a medium in the space between the antenna array and the metasurface, and a predetermined scanning angle of the antenna array.
