MULTICHANNEL ROTARY JOINT Russian patent published in 2019 - IPC H01P1/06 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used in antenna-feeder paths of multi-channel microwave range systems, in particular when building full-turn antenna posts with mechanical scanning of the radiation pattern. Multichannel rotary joint contains two waveguiding elements, united with each other coaxially on the bearing with the possibility of rotation relative to each other. One waveguiding element contains an insulated bracket with contact rings, and each waveguide element includes a housing with an internal cylindrical surface, a corner connection with a connector, conductors, and a round corrugated waveguide. Round corrugated waveguide of one waveguiding element is separated from a circular corrugated waveguide of another waveguiding element by a gap, forming one high-frequency transmission channel. Outer surface of a round corrugated waveguide and the inner cylindrical surface of the housing of each waveguiding element form a coaxial line. Coaxial line of one waveguiding element is separated from the coaxial line of another waveguiding element by a gap, together with the corner connection and the connector forming the second high-frequency transmission channel. In the housing of each waveguiding element, conductors are placed which are made with the possibility of contact with the conductors of another waveguiding element by means of contact rings, mounted on an insulated bracket on the outer surface of the housing of one waveguide element, forming low-frequency transmission channels.

EFFECT: technical result consists in providing the transmission of two signals in the microwave range, significantly separated from each other in frequency, and the transmission of control and power signals in the amount from 1 to N through one rotary group.
