FIELD: radio engineering, communication.SUBSTANCE: invention relates to stripline microwave antenna equipment, namely to a distribution system for a phased antenna array. The distribution system for FAA consists of two main and two additional linear power dividers with a subsequent division circuit, which are made on directional couplers combined with each other by means of phasing sections. Inputs of linear power dividers are connected to outputs of a summation-difference circuit having one summation input and one difference input. Outputs of the distribution system are made in the form of coaxial and stripline junctions; to some outputs of the directional couplers of additional linear power dividers there connected are matched loads represented by stripline casing-type microwave resistors. Structurally, the distribution system is made in the form of a layered structure containing a substrate with an applied pattern of central conductors of a symmetrical strip line installed between dielectric layers. Metal layers represent screens of the symmetrical strip line, on which output coaxial stripline junctions are fixed.EFFECT: formation of optimum amplitude distributions for summation and difference directivity patterns; possible implementation in centimetre and decimetre ranges of wave lengths.8 cl, 4 dwg |
