FIELD: microwave radio engineering.
SUBSTANCE: invention can be used as an antenna beamforming system in wireless communications, such as mobile communications, satellite communications, radio frequency identification devices. The multi-beam feed-through antenna array consists of control system 1 and absorbing surface 2 made with it on a single printed circuit board, close to which there is sub-array of irradiating elements 3, forming a spherical wave front, which is received by pass-through phased antenna array 4, which forms the radiation pattern in the required direction in accordance with the distribution control system specified.
EFFECT: reducing the influence of the phased array antenna control system on the characteristics of the antenna system, due to the use of an absorbing (impedance) surface that absorbs unwanted reflections of the microwave signal that occur between the irradiating subarray and the receiving part of the pass antenna array.
