DUAL-POLARIZED DIPOLE ANTENNA Russian patent published in 2017 - IPC H01Q21/26 

FIELD: radio engineering, communication.

SUBSTANCE: two-polarized dipole antenna comprises a radiator of two orthogonal dipoles located in a plane parallel to the reflector. Each arm of the dipoles is formed by a pair of conductors symmetrically bent relative to the longitudinal axis of the dipole, closed around each other at the feed point with one end and having a gap between the second ends which forms a rupture of the arm contour. The initial portion of each conductor adjacent to the feed point is rectilinear and parallel to the initial portion of the adjacent second dipole conductor and to the end portion of the second conductor portion of the pair adjacent to the gap. The essence of the solution lies in the fact that the initial portions of conductors are made with a length L = (0.07-0.15)⋅λ_mid, where λ_mid is the wavelength corresponding to the midfrequency of the frequency range, wherein the initial and end portions of each conductor are interconnected by an intermediate portion. The intermediate portion can be made rectilinear or in an arc.

EFFECT: improved matching of the dipoles with the supply cable and expanded operating frequency band.
