MIRROR ANTENNA FEED Russian patent published in 2007 - IPC H01Q13/02 

FIELD: antenna engineering.

SUBSTANCE: novelty is that conductor with inductive character of conductivity is secured in mirror antenna feed that has waveguide and reflector on protective dielectric shell installed outside waveguide coaxially with respect to the latter; this conductor functions to match shell and aperture of waveguide at a time and can be made, for instance, in the form of flat or wire ring, or in the form of a few thin-wire turns.

EFFECT: ability of matching high-quality feed in broad frequency band, enhanced antenna gain and polarization isolation.
