DESIGN OF A CURVED UHF ANTENNA ARRAY Russian patent published in 2021 - IPC H01Q21/00 H01Q13/18 H01Q23/00 

Abstract RU 2762320 C1

FIELD: antenna equipment.

SUBSTANCE: invention relates to ultra-high frequency antenna equipment and can be used as part of on-board radio location systems. The substance of the claimed solution consists in the fact that in the design of a curved UHF antenna array containing a rectangular waveguide curved in an arc and filled with a dielectric, wherein rectangular slits are cut on the outer side of the curve of said waveguide, the width of the waveguide decreases along the length thereof in the direction of propagation of the excitation signal, and the waveguide itself is formed by two symmetrically converging lines of circular metallised holes directly inside the dielectric made in the form of a flat uniform sheet and metallised on both sides, wherein the slits located on the surface of the waveguide are oriented longitudinally along the axis thereof and have a transverse displacement determined by the required amplitude distribution.

EFFECT: optimised design of an arc antenna, reduction in the weight and size characteristics (WSC) thereof, and complete automation of the control of the antenna beam in a wide scanning sector with high operating speed.
