MODULE OF PHASED TRANSMISSIVE ANTENNA ARRAY Russian patent published in 2012 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: module foundation of transmissive PAA is performed in a form of rigid plate containing printed conductors with bonding areas and pins installed along the plate on both sides between which there are PAA elements on the plate. The housings are mounted on the plate and bonded to it, bonding areas of PAA element printed-circuit board are connected to the outputs of magnetisation winding and soldered to bonding areas of module foundation of transmissive PAA. PAA element passes electro-magnetic waves polarised by circle and 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. PS 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 "П"-shaped ferrite clamps located one by one on each FR plane. Each DR has cylindrical part inside and outside the radiator wave guide, conical part and cylindrical matching transformer at the end.

EFFECT: increase of PAA element positioning accuracy in longitudinal as well as lateral directions of module foundation, extension of beam scanning sector of regular antenna array, increase of transmissive PAA module resistance against external mechanical effects.
