COAXIAL FIN-LINE COMMUNICATION Russian patent published in 2007 - IPC H04B3/06 

FIELD: radio communication engineering.

SUBSTANCE: device has coaxial cable having its external conductor manufactured as flexible braid composed of strands arranged at an angle of 30-50°, forming rhombic windows in external conductor being 50-100 times as large as empty space between conductors in places of their overlapping. The windows are arranged in chessboard order along cable axis, insulation is manufactured from porous polyethylene, and the internal conductor is continuous single-wire one adjacent close to insulation without gap. Being arranged in chessboard order along the axis, the rhombic windows give uniform electromagnetic energy portion radiation in space around the cable usable as emitting aerial. Required losses level by communication and longitudinal attenuation regulation is achieved by selecting braid width, radius and angle, and also distance between the rhombic windows.

EFFECT: reduced losses on communication, resistor noise with appropriate durability and flexibility being retained.
