These signals are passed through the corresponding summation blocks 3, including the common-mode and anti-phase adders 2, ideal distribution multipoles 4, and phase shifters 5, as a result of which the amplitude-phase distribution is created on the radiators 1 corresponding to one of the new wave types. The goal is achieved by exciting different types of waves in a rectangular waveguide with a one-to-one correspondence between the number of the type of wave and the number of the input of the diverting device. 1 hp f-ly, 4 ill.

The invention relates to antenna technology and can be used in waveguide modeling of antenna systems.

The purpose of the invention is to simplify the design in waveguide modeling.

The connecting device for the line of emitters contains emitters 1, in-phase and anti-phase adders 2, summation blocks 3, ideal distribution multi-poles 4, phase shifters 5 by 180 °. CR of a carbon waveguide is not shown.

The development device operates as follows.

When a microwave signal is applied to one of the inputs of an isolating device for a line of emitters, the microwave signal passes through the corresponding summation blocks 3, including in-phase and phase-in adders 2, ideal distribution multipoles 4, phase shifters 5, and on the radiators 1 creates an amplitude-phase distribution corresponding to one. from waveguide types of waves.

Thus, by supplying microwave signals alternately or simultaneously to the inputs of the spreading device, it is possible to excite various types of waves in a rectangular waveguide with a one-to-one correspondence between

type number and input number of the expansion device.

Thus, a reduction in the number of blocks forming a spreading device for a line of emitters is achieved, i.e. simplification of the design, while ensuring the possibility of wave simulation of the HEADLIGHTS.
