FRACTAL RADIATOR Russian patent published in 2017 - IPC H01Q9/34 

FIELD: radio engineering, communication.

SUBSTANCE: rectal radiator consists of two metallized dielectric boards one above the other. The upper metallized dielectric board having a cruciform shape with four vibrator arms, and a screen, are connected via a balancing system, consists of two orthogonally connected metallized dielectric boards with conductive strip lines. To reduce the size of the fractal radiator, the edge of the metallization of the vibrator arms has a fractal structure. And to reduce its weight, the upper metallized dielectric board is cut off along the metallization contour with a small shift. There are perforation holes of different sizes in the metallization of the upper metallized dielectric board and the screen. To obtain a uniform radiation pattern in the metallization of the upper metallized dielectric board, narrow transverse slots are made.

EFFECT: producing a radiator of smaller mass, reduced dimensions, with a frequency working band with unidirectional radiation and uniform directional pattern in the frequency working band.
