ANTENNA ARRAY WITH A FREQUENCY SCANNING Russian patent published in 2016 - IPC H01Q21/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to microwave radio engineering. Peculiar feature of the disclosed antenna array with a frequency scanning is that antenna array is made up of three mechanically mating plates, in the first plate and on one side of the second plate there are the kite channels of the waveguide, which are made by milling to a depth in Passerini waveguide channel, and on the other side of the second and third plates there are the channels of the waveguide-slot lines, electric connection of kite waveguide with waveguide-slot lines is done via communication elements of waveguide channels of directioned couplers in general narrow wall of two waveguides, and the communication elements in directional couplers are made in the form of inclined slots, while slit radiators in blends are made in the form of straight slots excited by U-shaped conductors of half-wave length.

EFFECT: usage of the antenna array in a wide wavelength range.
