MULTICHANNEL MICROWAVE ROTATING CONNECTION Russian patent published in 2021 - IPC H01P1/06 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, particularly, to multichannel rotating joints. Multichannel microwave rotating connection consists of single-channel rotary joints installed coaxially one above another, each of which is made on the basis of coaxial line with quarter-wave short-circuited loops in the form of radial line and matching transitions at ends. Outer and central conductors of coaxial line comprise quarter-wave throttle clearances, radial line has variable height, and through central conductors of single-channel connections through hollow metal rod of cylinder shape passes through rotating to fixed part of the structure, which forms throttle clearances with fixed central conductors. Movable inputs of single-channel rotating connections are brought to the rotating part of the device structure by means of coaxial feeders, passing except for the feeder of the upper one-channel connection through the internal cavity of the rod.

EFFECT: simplified design, increased electrical isolation between channels, as well as structural design, providing the possibility of additional elements output, in particular, a fiber-optic communication line, from a rotating to a fixed part of a path through an axis of rotation of the device and a coaxial installation on the side of its fixed part of additional movable connections.
