DIAGRAM-FORMING DEVICE Russian patent published in 2021 - IPC H01Q21/00 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology and is intended for creating an antenna array with a fan-shaped radiation pattern and maxima oriented at angles to the grid axis. The diagram-forming device contains four emitters numbered from left to right, four 3-decibel couplers, each of which has an input, decoupled, galvanic and connected shoulders, and the couplers are similarly oriented in the layout space and grouped in pairs in the upper and lower rows of the structure, while the connected shoulders of the couplers of the upper row are connected to the first and second emitters, and the galvanic shoulders of these couplers are connected to the third and fourth emitters, respectively, identical double-arm elongated U-shaped conductors and identical narrow elongated closed ring conductors, electromagnetically connected to U-shaped conductors along their entire length, are introduced into the device.

EFFECT: more advanced device with an increased broadband width of its channels within the working section of the frequency range.
