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

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna devices having at least two directional patterns, and can be used in communication systems to receive broadband microwave signals, including the millimeter range, for example, in on-board space communication systems. Receiving multi-beam active phased array antenna (APAA) is configured to supply the required supply voltage to all circuit elements requiring power and contains an input module and an output module. Input module contains at each n-th input (N≥n≥2) the corresponding n-th group of the series-connected emitter (module inputs and APAA as a whole), low-noise amplifier, M-channel power divider (M≥2) and in parallel connected to it the first inputs M of phase shifter. Second inputs of the phase shifters are connected in parallel to the control unit to obtain certain phase programs. Input module also contains M beam adders. Output of each m-th phase shifter of each n-th group is connected to the n-th input of the m-th beam adder. Outputs of the totalizers are the outputs of the input module. In each n-th group, the first input of the down-mixer is connected to the output of the low-noise amplifier, the second input of which is connected to the local oscillator, and the output through the compensating amplifier is connected to the input of the divider.

EFFECT: technical result consists in expanding the APAA working band.
