MULTI-BEAM ANTENNA Russian patent published in 2017 - IPC H01Q3/00 

FIELD: radio engineering, communication.

SUBSTANCE: multi-beam antenna in which transmission channel from focal device (2) to receivers of transmitting partial amplifiers of amplifier array (1) is designed as a light source modulated by transmitted radio signal. Light radiation is generated by pairs of closely spaced LED lasers with different wavelengths placed in transceiver modules (8, 10) on the focal surface (4). Receivers of transmitting partial amplifiers are designed as two closely located photoreceivers with appropriate filters. A ray (5) of double polarisation is formed by the module (8). Light emission with amplitude distribution (7) illuminates photodetectors of transmitting partial amplifiers on aperture (A). A ray (6) of double polarisation is formed by the module (10). Light emission with amplitude distribution (9) illuminates photodetectors of transmitting partial amplifiers on aperture (A1). The aperture (A1) may not be aligned with the aperture (A).

EFFECT: reduction of operating costs.
