DISTRIBUTOR FOR PHASED ANTENNA Russian patent published in 2009 - IPC H01Q3/26 

FIELD: physics; radio.

SUBSTANCE: invention concerns radio engineering, industry and can be used in guided-wave microwave frequency antenna equipment as a part of distributive systems for the phased array antenna (PAA). The new thing in the PAA distributor is choosing of sizes of transitive attenuations of the directional couplers of additional strips of the directional couplers from a forming condition of the peak distribution corresponding to a difference pattern with lowered level of lateral lobes in a plane of an arrangement of the distributor on their exits, and also paired connection of exits of the basic and additional strips of the directional couplers where microwave energy is divided, to 4K input terminals of hybrid arrangements.

EFFECT: provision of independent forming of optimum peak distributions separately on a total and difference channels of the PAA distributor, and increase in factor of a signal transmission in a "transmission" mode at use of hybrid arrangements for splitting of signals on total and difference channels, and also in extension of a working range of frequencies, design simplification, shortening of overall dimensions and weight.
