BROADBAND Z-ANTENNA ON FEEDER Russian patent published in 2019 - IPC H01Q9/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the antenna equipment, in particular to vibratory broadband wire antennas. Broadband Z-antenna on the feeder (Fig. 1) contains the band vibrator, which each arm 1 consists of arranged in the same plane pairs 2 of triangular lower and upper frames 3 by adding from the external ends diverging from the power points “a”-”b”of conductors 4 with a length of 0.25λ_max, triangles 5 sides conductors with lengths of 0.25λ_av., directed to the “o”-“o₁” axis of symmetry. Lower frames 3 arms 1 are attached to the conductors of the tubular symmetrical short-circuited bridge with a length of 0.25X_max. To create the triangular frames 3 identical upper system 8, as well as the common two-wire bearing feeder 9 from the feeding points “a”-”b” an additional balancing short-circuited bridge 7 with a length of 0.25λ_av. is introduced. Frames 3 are formed by the added conductors 5 connection to the short-circuited bridges 6, 7 nearest conductors. Upper and lower triangular frames 3 systems 8 are symmetrically moved apart with respect to the feeding points “a”-”b” at a distance of “l”, commensurate with 0.25λ_max-0.25λ_av., along the feeder 9, providing the triangles 5 sides conductors displacement in the direction to the balancing bridges 6, 7 short-circuited jumpers 10. Technical result is achieved by the vibrator with an increased adsorbing area active structure formation from the arms broadband elements due to the design original implementation with the component elements functions non-standard use.

EFFECT: is the broadband antenna development, characterized by high gain, increased mechanical strength and simplified manufacturing technology, having a design, providing the elements in the band dipole arrangement rigid position and the antenna stable mounting when placed as the complex antenna systems components and with individual use.
