ELEMENT OF PHASED TRANSMISSIVE ANTENNA ARRAY Russian patent published in 2012 - IPC H01Q21/00 H01P1/19 

FIELD: radio engineering.

SUBSTANCE: device contains receiving and apertural dielectric radiators (DR), wave-guiding ferrite rotation phase shifter (PS) of faraday type and housing in a form of thin-wall shell. Rotation phase shifter consists of ferrite rod (FR) in a form of N -plane prism (N≥4) located together with winding of its longitudinal magnetisation inside magnet core in a form of N "П"-shaped ferrite clamps located one by one on each FR plane. Wave guide of PAA element includes wave guide formed by film of current-conducting coating of FR side surface, radiator wave guides, matching and connecting wave guides. Between the ends of FR and ends of DR there are dielectric inserts in form of washers made from material with dielectric capacitance ε_v=9.5 … 10.5. Ferrite unit is centered in the housing by dielectric washers the outer surface of which like ferrite clamps ledges is done by a form of housing inner surface. Dielectric radiator has a form of round bar at the end of which there is a matching transformer.

EFFECT: reduction of crosscut dimensions, reduction of microwave losses level, increase of PAA amplification factor, structure simplification, increase of its processability, strength and resistance against impact and vibration effects.
