CIRCULAR SLOTTED WAVEGUIDE MODULE FOR MIMO TECHNOLOGY AND METHOD OF ITS MANUFACTURING Russian patent published in 2024 - IPC H01P3/06 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, in particular to microwave waveguides. Circular slotted MIMO waveguide comprising two plastic pipes (1), the inner part of which is a hollow structure, wherein two said plastic pipes (1) are arranged in parallel in their longitudinal direction; outer conductor (2), wherein said outer conductor (2) covers two said plastic pipes (1), and said two plastic pipes (1) form a single structure, outer surface of said outer conductor (2) is provided with several first grooves (21) and second grooves (22) in the longitudinal direction of said outer conductor (2), said first grooves (21) uniquely correspond to second grooves (22), wherein said first grooves (21) and said second grooves (22) are arranged orthogonal; protective layer (3), wherein said protective layer (3) covers said outer conductor (2); two said plastic pipes (1) are filled with filler (4); relative permittivity and properties of material used for said filler (4) and two said plastic pipes (1) are identical.

EFFECT: increased signal coverage area, increased range of signal transmission, increased efficiency of production.
