MULTICHANNEL ROTATING JOINT Russian patent published in 1999 - IPC

FIELD: microwave engineering; receiving and transmitting electromagnetic energy from moving parts of antennas to fixed parts of microwave channels. SUBSTANCE: newly introduced in device are bushings in the form of truncated cones which are fitted onto ends of coaxial lines and absorbing rings placed on ends of adjacent coaxial lines. Adjacent ends of adjacent lines have bushings of different types: some of them incorporate internal choke coils and other ones have no choke coils; bushing height is calculated from equation given in description of invention.
