ANTENNA ARRAY ON A RADIAL WAVEGUIDE Russian patent published in 2021 - IPC H01Q21/24 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment, in particular, to broadband annular antenna arrays, and can be used in various broadband radio engineering systems for radio location, satellite and mobile communication. The technical result is achieved by the fact that the antenna array on a radial waveguide comprises an emitting system formed by printed low-quality patches located equidistantly along concentric circumferences lying in a plane parallel to the plane of the radial waveguide, wherein the centres of the concentric circumferences are aligned with the geometric centre thereof; a matching system formed by coaxial pins located perpendicular to the plane of the emitting system, and a non-uniform dielectric filling the space between the emitting, matching systems, and the radial waveguide.

EFFECT: reduction in the level of side lobes of the directivity pattern, decrease in the voltage coefficient of the standing wave, simplification in the antenna array matching.
