DUAL BAND ANTENNA SYSTEM Russian patent published in 2022 - IPC H01Q21/00 

FIELD: microwave technology.

SUBSTANCE: invention relates to microwave technology, namely to antenna systems with sum-difference signal processing. The effect is achieved by the fact that a dual-band antenna system, including a waveguide-slot antenna array of the high-frequency range, made in the form of a multi-level system of waveguides and containing a waveguide power distribution circuit and a radiating antenna array, divided into several sub-arrays, the radiating elements of which are made in the form of through holes in wide walls of parallel rectangular radiating waveguides forming the first level of the waveguide-slotted antenna array, perpendicular to which, at the second level of the waveguide-slotted antenna array, one for each sub-array is located to the exciting waveguide.

EFFECT: formation of eight independent output microwave signals with an increase in the gain and a decrease in the level of the side lobes of the high-frequency range antenna system.
