FIELD: radio engineering. SUBSTANCE: communication center for generation of reception of a cascade of radiated beams with an angular divergence has an antenna array of radiating units making up a multi-unit antenna and a directivity pattern shaper; the directivity pattern shaper has a passive multi-port network, having the first lateral side accommodating a great number of beam ports for electric signals corresponding to the beams and the second lateral side carrying a great number of antenna ports corresponding to the radiating units; each beam port is connected to a great number of antenna ports via the multi-port network of power dividers a phase shifters, whose phase shifts are multiple on the whole of the preset constant so as to create a beam array, in which the multi-unit antenna has a triangular or hexagonal symmetry, and the beam array has a triangular or hexagonal symmetry. EFFECT: reduced power between the adjacent beams in the directivity pattern in field intensity in the distant zone at a reduced weight and consumer electric power. 27 cl, 14 dwg
