The invention relates to an antenna design and may be used for effectively concentrating radiation emitted by a distributed source on an object (4) placed in the focal area (5) of the antenna. The claimed technical result is achieved in a multipurpose device for transmitting radiation from a source (3) to an object (4) comprising two antennas (1), each designed as a truncated segment of a curved surface, established with the formation of the joint focal zone (5) reconfigurable, concentration and volume by varying the distance between the antennas, a distributed source of radiation provided in the aperture plane of at least one of the antennas or in one of the focal areas of each antenna, and an object placed in the combined focal area of the two antennas.
