ANTENNA DEVICE Russian patent published in 2019 - IPC H01Q1/28 

Abstract RU 2695923 C1

FIELD: radio engineering, communication.

SUBSTANCE: antenna device contains a waveguide power distribution scheme, a radiating curtain, a conductive material shim, and a flat radiotransparent blister. The waveguide power distribution scheme contains launch waveguides of the waveguide power distribution scheme, supply waveguides of the waveguide power distribution scheme and waveguide power distribution scheme dividers. The radiating curtain contains parallel-arranged radiating waveguides with radiating elements of radiating waveguides. Radiating elements of radiating waveguides are longitudinal slits in the wide walls of radiating waveguides. Launch waveguides of waveguide power distribution scheme are arranged perpendicularly to the radiating waveguides. Radiating waveguides are launched by launch waveguides of waveguide power distribution scheme through inclined slits in their common wide walls. The launch waveguides of waveguide power distribution scheme are fed using the supply waveguide of waveguide power distribution scheme and the dividers of waveguide power distribution scheme. A conductive material shim is designed to ensure a constant gap between the surface of radiating curtain and flat radiotransparent blister. Rectangular through holes are made in the conductive material shim. A conductive material shim is installed between the surface of radiating curtain and flat radiotransparent blister. Rectangular through holes of conductive material shim are placed opposite the radiating elements of the radiating waveguides. A flat radiotransparent blister represents a sheet of dielectric material with a low value of dielectric loss tangent.

EFFECT: creation of antenna device technological design, that provides an increase in its mechanical strength, improvement in its range properties and reduction of lateral radiation level.
