FIELD: aerial technology; radiocommunication and TV systems. SUBSTANCE: two-range aerial has S-shaped loop vibrator and spatial logoperiodical structure; both are fed by common feeder. Wires 1 and 2 of loop vibrator are connected at points 3-3 to wires 4 and 5 of distribution line of logoperiodical structure. Moreover, wires 1 and 2 are disposed at different sides from continuous wire 6 of vibrator. Wires 4 and 5 of distribution line are mounted at an angle one to the other (distribution line is made in form of V letter). Arms of vibrator of logoperiodical structure made in form of sections of straight wires 7 or trapezoids 8, are disposed at two semi-planes which form double-face angle. EFFECT: improved coefficient of direction action at high-frequency range of aerial. |
