BORODIN'S SLOTTED WAVEGUIDE ANTENNA Russian patent published in 2013 - IPC H01Q13/00 

FIELD: radio engineering, communication.

SUBSTANCE: slotted waveguide antenna relates to microwave equipment and specifically to slotted waveguide linear antennae and arrays thereof with beam scanning in a plane perpendicular to the lines and can be used in radio engineering systems, including in air-traffic control systems, communication, radar and radio navigation systems, based on both fixed and mobile objects. The antenna includes lines which form an array, having a rectangular waveguide with a terminal load, wherein on the narrow wall there are transverse slits whose spacing is close to half the wavelength in the waveguide, the transverse slits on the narrow wall having ends on the wide walls of the waveguide, the ends of the transverse slits on the wide walls of the waveguide having different elongation on the wide walls.

EFFECT: attenuation of cross-correlation to the level of low side lobes, resulting in high efficiency, gain, low labour input, cost and high noise-immunity of radar stations.
