SUBSTANCE: proposed transceiving antenna disposed in plane perpendicular to screen has matching device and active electromagnetic energy radiators made in the form of three asymmetric dipoles; these active electromagnetic energy radiators are mounted in tandem one after another and spaced 0.1 - 0.25λ l apart, where λ l is wavelength of frequency-band lower boundary; electric lengths of electromagnetic energy radiators equals 0.55-0.65λ l , 0.4-0.55λ l , and 0.15-0.35λ l , respectively; mounted on screen at side of active radiator, 0.15-0.35 λ l in length, at distances of 0.13-0.18λ l and 0,25-0.3λ l , respectively, are two passive dipoles, 1.1-1.3λ l and 0,55-0.65λ l in length and passive dipole, 0,25-0.35λ l in length, is installed at distance of 0,2-0.25λ l at side of active radiator, 0,55-0.65λ l in length.
EFFECT: ability of generating directional pattern in azimuthal plane; extended passband toward low frequencies.
