MULTIBEAM TRANSMITTING ACTIVE PHASED ANTENNA ARRAY Russian patent published in 2020 - IPC H01Q25/00 

FIELD: antenna equipment.

SUBSTANCE: disclosed technical solution relates to antenna engineering and can be used in microwave communication systems. Multibeam transmitting APAA comprises M multichannel power dividers (D). Multichannel output of each m-th (2≤m≤M) D is connected to the corresponding m-th information input of n-th (2≤n≤N) transmitting module (TM). Output of each n-th TM is connected to the corresponding n-th emitter (EMR). Inputs of dividers form multi-channel input of antenna array, and emitters – its multibeam output. Control input of each n-th TM is multichannel and is connected to the corresponding n-th output of the control device (CD). Each TM comprises M parallel phase shifters (FS), information input of each of which is connected to corresponding m-th information input TM, and output - to input of adder (C), connected to output of TM through power amplifier (PA). Each n-th TM comprises a device for addressing and controlling phase shifters (ACP), the input of which is connected to the control input TM, and the output is connected to the control input of each of the M phase changers of this TM. Connection of each n-th output of CD to control input of n-th TM is performed by means of two detachable connections, some parts of which are installed respectively at input and output of n-th control cable, others – respectively at control input of n-th TM and n-th output CD. Detachable connections contain control contacts and address contacts, one of which is "common" and (K-1) combined (N≤2^(K-1)). At that, on one of the parts of one of the detachable connections there is an individual n-th combination of address contacts by means of short-circuit to the "common" address contact defined from (K-1) combined address contacts to set individual binary address of each n-th TM (and, respectively, each of its phase changers) during operation of assembled antenna array.

EFFECT: simplified assembly, adjustment and debugging of the system, as well as considerable reduction of costs for maintenance and repair.
