FLAT ARRAY OF DIFFRACTION RADIATION ANTENNAS AND POWER DIVIDER USED IN IT Russian patent published in 2012 - IPC H01Q13/00 H01P5/12 

FIELD: radio engineering.

SUBSTANCE: flat antenna array of diffraction radiation comprising a grid of guide systems of surface waves, such as a rectangular dielectric waveguide arranged at the angle to a 2D grid of periodical nonconformities of a comb type, and an exciter of surface waves in the form of a compact power divider of waveguide type. The power divider of waveguide type comprises an H-flat waveguide tee with matching elements as a capacitance rod and a matching wedge, two symmetrically arranged serial waveguide-slot power dividers with communication slots of different length, which connect the manifold waveguide with output waveguides equipped with dielectric inserts of various length made as a whole with dielectric waveguides of the diffraction radiation antenna array, the extreme output waveguides have a complete link to the manifold waveguide via a matched 90-degree bend of the waveguide.

EFFECT: compact, technological, flat array of radiators, with high coefficient of antenna surface usage.
