ANTENNA ELEMENT OF PHASED LEAD-THROUGH ANTENNA ARRAY Russian patent published in 2008 - IPC H01Q21/00

Abstract RU 2322737 C1

FIELD: antenna engineering; antennas for lead-through phased microwave antenna arrays incorporating provision for electric scanning of beam.

SUBSTANCE: proposed antenna element of lead-through phased antenna array has electric radiators and phase shifter incorporating magnetizing coil disposed within magnetic circuit, as well as cylindrical ferrite rod installed inside magnetizing winding. Dielectric radiators have cylindrical part and are rigidly fixed on one end to ends of cylindrical ferrite rod, and their loose end parts are made in the form of truncated cones, diameter of truncated cone base being smaller than that of dielectric radiator cylindrical part. Central ferrite rod and dielectric radiators are inserted in common section of metal-plated round waveguide. Cylindrical ferrite rod and dielectric radiators are made of material characterized in almost equally high dielectric constant.

EFFECT: reduced microwave energy loss.
