BROADBAND SYMMETRICAL VIBRATOR IN PRINTED DESIGN Russian patent published in 2022 - IPC H01Q9/00 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology, in particular to broadband symmetrical vibrators in printed form. The effect is achieved by the fact that a broadband symmetrical printed vibrator, made on a substrate containing a screen, a two-wire symmetrical line forming a short-circuited loop, which is connected to the vibrator arms on the one hand, and to the screen, on the other hand, the supply line, the vibrator arms and supply conductors of a short-circuited loop are located on different sides of the substrate, in this case, the supply line is made in the form of a symmetrical strip line, the inner conductor of which is connected to one of the vibrator arms by means of a jumper, and the screen is installed perpendicular to the substrate, characterized in that a matching printed element is introduced, located on the inner part of the substrate, above the vibrator arms, forming a three-circuit system.

EFFECT: improved transmission line-to-load matching over a wider frequency band.
