TWIST REFLECTOR Russian patent published in 2021 - IPC H01Q15/24 

FIELD: ultra high frequency equipment.

SUBSTANCE: invention relates to ultra high frequency equipment, in particular, to twist reflectors for rotating the polarisation plane of an incident electromagnetic wave (EMW). The technical result is achieved by the fact that the twist reflector containing a dielectric substrate, a metal screen, and at least two polarisation structures facing a flat EMW emitter and oriented at an angle of 45° to the wave polarisation vector is characterised by the fact that the polarisation structures are located on the substrate and constitute arrays of discretely arranged printed reflective elements, wherein one structure operating in the high frequency range is formed by identical rectangular elements placed in the nodes of a rectangular grid parallel to each other, and the other structure operating in the low frequency range is formed by identical rectangular loop elements placed in the nodes of a triangular or rectangular grid around groups of rectangular elements of the high frequency range structure parallel to the long sides thereof.

EFFECT: increase in the efficiency of the apparatus with the maintained reflective properties during operation in different frequency ranges.
