FREQUENCY-CONTROLLED ANTENNA

摘要

FIELD: microwave radio engineering; radar frequency-controlled antennas. ^ SUBSTANCE: proposed antenna is made in the form of flat array of linear radiators connected to power splitter in the form of sine-wave configured line. Components coupling power splitter with linear radiators are divided at antenna input into two groups so that longitudinal axis incorporating all even-numbered coupling members is offset relative to axis incorporating all odd-numbered coupling members by integer odd number of quarter-wavelengths in sine-wave line of power splitter. Phase mismatch occurring in this case is compensated for by respective difference in input section lengths of even- and odd-numbered linear radiators. ^ EFFECT: reduced space requirement, improved matching and performance characteristics of antenna and radar as a whole. ^ 2 cl, 2 dwg
