VIBRATOR ANTENNA SYSTEM Russian patent published in 2023 - IPC H01Q9/28 

FIELD: antenna systems.

SUBSTANCE: printed vibrator antenna system contains a rectangular dielectric substrate 1 with front 2 and back 3 surfaces, having a pair of large 4, 5 and a pair of small 6, 7 sides. On the front surface 2, parallel to the large side 4, in close proximity to it, two identical elongated narrow conductors are made, divided in the middle by gaps 8 into two coaxial halves 9, 10 and 11, 12 with adjacent 13, 14 and 15, 16, as well as remote 17, 18 and 19, 20 ends. In this case, the orientation of the halves 9, 10 and 11, 12 on the common axis is opposite. Near the other large side 5, three identical two-channel equal-amplitude power distributors are made without ballast resistors, connected to each other according to an aluminum alloy herringbone ladder, forming a 4-channel common-mode power divider. The divider input is located on the large side 5 and is the input of the antenna system. Two spaced apart outputs 28 and 32 of the divider are connected to adjacent ends 16 and 13 of halves 12 and 9 via two identical two-stage segments of transmission lines 30 and 34, respectively. Two adjacent outputs 29 and 33 of the divider are connected by similar two-stage segments 31, 35 with adjacent distant ends 19 and 18 of halves 11 and 10, respectively.

EFFECT: creation of a more compact and advanced printed linearly polarized vibrator antenna system with a differential radiation pattern having a pronounced saddle in the direction perpendicular to the end of the large side.
