Abstract

The invention relates to antenna technology. The purpose of the invention is to simplify the structure during waveguide modeling. The developing device contains a rectangular waveguide. in the cross section of which there are N emitters 1, summation blocks 3, consisting of in-phase and phase counter adders 2, ideal distribution multi-poles 4 O and phase shifters 5 by 180. When alternately or simultaneously applying microwave signals to the inputs of the decoupling device, these signals pass through the corresponding summation blocks 3, including the in-phase and anti-phase adders 2, ideal distribution multipoles 4 and phase shifters 5, as a result of which the radiators 1 produce amplitude phase distribution corresponding to one of the waveguide types of waves. 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 developing device.

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 drawing shows a structural diagram of the development of a swivel device for a line of emitters.

The device contains emitters 1, in-phase and anti-phase adders 2, summation blocks 3, ideal distribution multipoles 4, phase shifters 5 through 180 °. The rectangular waveguide is not shown.

Development device for the line of emitters works as follows.

When a microwave signal is applied to one of the inputs of the expanding device, the microwave signal passes through the corresponding summation blocks 3, which include phase-to-phase 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, applying alternately or simultaneously C8H signals to the inputs of the developing device, you can excite different types of waves in a rectangular waveguide with a one-to-one correspondence between the type number and the input number of the developing device.
