COAXIAL FEEDER LINE Russian patent published in 2008 - IPC H01P5/02 H01P3/08 

FIELD: physics.

SUBSTANCE: invention concerns antenna and feeder equipment and can be applied in communication equipment and microwave instruments and devices. Coaxial feeder line features internal conductor in the form of cylindrical spiral and external conductor in the form of cylinder with at least two through slits positioned symmetrically along guide lines, and includes at least two broken ring conductors embracing external conductor and distanced from each other by at least one sixth slow wave length. At one end of coaxial feeder line cylinder parts separated by slits can be interconnected by radial bridges. Coaxial feeder line shows abnormal dispersion and allows electromagnetic wave propagation at phase velocity with thermal build-up of oscillation frequency.

EFFECT: propagation of electromagnetic waves at phase velocity with thermal build-up of oscillation frequency.
