FIELD: physics, radio. ^ SUBSTANCE: invention is related to the field of radio engineering and may be used in multichannel systems of cellular communication. Antenna device comprises transmitting antenna array from N radiators, N1 - channel power divider, inlet of which is inlet of device, receiving antenna array from M radiators and power divider, M inlets of which are connected accordingly to M radiators of receiving antenna array, and M1 outlets of power divider are accordingly device outlets. In order to achieve technical result, the first diagram-forming circuit is introduced, which forms N distributions at the outlet, which are own vectors of channel power matrix, N inlets of which are connected accordingly with outlets of N1 - channel power divider, which is arranged with controlled coefficient of division, N outlets of the first diagram-forming circuit are connected accordingly to N radiators of transmitting antenna array, power divider with M inlets and M1 outlets is arranged in the form of the second diagram-forming circuit, which transforms system of M1 own vectors of channel power matrix at the inlet from M radiators in system of M1 independent outlets. ^ EFFECT: increased safety of processed items with simultaneous simplification of design and reduction of power inputs. ^ 5 cl, 10 dwg |
