Zusammenfassung: | FIELD: radio and television broadcasting and communication devices operating in very high- frequency band. SUBSTANCE: antenna made in the form of two wire turns disposed on sides of two squares arranged along common diagonal has two-wire power line connected to any of two closest opposite sides of relatively open squares. Additional second, third, and next two-turn assemblies are coaxially arranged in parallel with two first turns one after another along axis perpendicular to common diagonal and crossing its center. Two- wire power line is connected in series with first, second, and next turns. Distance between first, second, and next turns may amount to quarter-length of electromagnetic wave; first turns are shortened, third and next ones are elongated relative to second turns whereto two-wire power line is connected. Linear dimensions of first, second, and next turns and distances along two-wire power line at points of its connection to turns vary obeying logarithmic law; first, second, and next turns are crosswise connected to this line. EFFECT: enhanced directive gain. 5 cl, 3 dwg |
