ROTARY CONNECTION Russian patent published in 2016 - IPC H01P1/06 

FIELD: radar.

SUBSTANCE: invention relates to radar engineering, particularly, to antenna-feeder system devices, used for transmitting microwave energy between the fixed part of the radar station, for example, stationary (fixed) transmitters, receivers, and rotary antenna system. Connection includes coaxial lines in the form of movable relative to each other cylinders, excitable at the points, evenly distributed along the perimeter at the ends of cylinders, adjustable elements and two-stage dividers, representing symmetrical tees connections, the output arms of which are made in the form of transformers. At that the transformers being the output arms of the first stage tees, are made of several series-connected non-resonance transmission line sections with different wave resistance, decreasing from the first stage tee inlet to the second stage tees inlets, and transformers being the output arms of the second stage tees, represent non-resonance transmission line sections, with variable impedance, increasing from the tees inputs to the places of connection to connected coaxial lines.

EFFECT: technical result consists in increase of operating frequency tuning capabilities in a wide range and reduction of dimensions while maintaining good matching and low losses of microwave signal.
