RECEIVING MULTI-BEAM ACTIVE PHASED ANTENNA ARRAY Russian patent published in 2018 - IPC H01Q25/00 

FIELD: antenna.

SUBSTANCE: invention relates to antennas having at least two directional patterns, and can be used in communication systems, requiring high immunity to electromagnetic interference, including in microwave systems. Multi-beam active phased array antenna (APAA), configured to supply the required supply voltage to all circuit elements, requiring food, contains on each of the N (N≥2) inputs n group of a series-connected radiator, low-noise amplifier, M-channel divider and in parallel connected to it the first inputs of M phase shifters (M≥2, N≥2). In addition, the second inputs M×N phase shifters are connected in parallel to the control unit. LFAR contains M beam adders 5 (Σ) with N inputs in each. Output of each m phase shifter of each n channel - to the n input of the m adder. Moreover, the output of each beam totalizer through a corresponding electron-optical converter is connected to an optical combiner (OC). Output of the OC is connected to the input of the optical divider (OD). To the output of the OD, M selective photodetectors (SFP) are connected in parallel. Output of each m SFP is connected to the corresponding AFLR output via a corresponding output amplifier (Y) to transmit the received information to the consumer.

EFFECT: high immunity to electromagnetic interference.
