FIELD: radio engineering, communication.
SUBSTANCE: radar antenna, having at least one radiator operating in a given frequency band, placed in front of radiators in one plane of the a frequency selection device with band characteristics which enable to transmit electromagnetic radiation in the operating frequency band, and reflect radiation outside said band, between the radiators at a distance therefrom in one plane, there are linear arrays of identical dipoles which form a flat two-dimensional periodic mesh structure.
EFFECT: reducing the scattering cross-section of the antenna in the operating frequency band thereof.
