WIRE ANTENNA Russian patent published in 2002 - IPC

FIELD: ultrashort-wave radio broadcasting and communication devices. SUBSTANCE: antenna that has two squareshaped wire turns disposed in same plane along common diagonal on its both sides to constitute two circuits held open throughout entire length and two-wire power line is provided in addition with second, third, and other pairs of turns and has its two-wire power line connected to open sides at contacting points of squares. As an alternative two-wire power line may be connected to second turns only; distance between first, second, third, and other turns amounts to quarter of electromagnetic wavelength; first turns are shortened while third and other ones are elongated relative to second ones by a few percent. In addition linear dimensions of first, second, and other turns as well as distance along two-wire power line at points of its connection vary obeying logarithmic law. EFFECT: enhanced directivity of antenna. 3 cl, 3 dwg
