The invention relates to antenna technology, namely to diagram-forming devices (DOW) of multi-beam antenna arrays.

The purpose of the invention is to increase the number of beams of the radiation pattern and device breakdown.

FIG. 1 shows a scheme for connecting a DOW reflection type to radiators; in fig. 2 - DOW scheme of reflective type.

The DOW 1 of the reflective type is connected to the radiators 2 through Y-circulators 3.

Reflection-type DOW contains a summation block 4, consisting of hybrid adders 5 with equal power division, an ideal distribution multi-terminal 6, multi-terminals, phase shifters 8 with phase shifts if,

, / 4, where Ng is the number of radiation patterns,; - serial number of phase shifter, phase shifters 9 s

/ i,

phase shifts (r - t-).

Dow reflective type works as follows.

The signal from the microwave generator is fed to the free input of the U-circulator 3, connected by one arm to the / -th radiator 2, and the other arm to the / -th input of DOW 1 of the reflective type. Zatem.m signal passes through the hybrid adder 5 of the block 4 summation, the ideal distribution multipole 6, multipoles 7 and phase shifters 8 and 9. Next, the signal, through the hybrid adder 5, enters the input of the Y-circulator 3 connected to the DOW 1 of the reflective type At the same time, the outputs of the U-circulators 3, connected to the radiators 2, receive signals of equal amplitude with phase distribution, determined by the number of the U-circulator 3, connected to the microwave generator. On the k-th radiator 2, a signal arrives with a phase shift Φ 2l // g /, U ,.
