ARRAY OF WAVEGUIDE-HORN RADIATORS, METHODS OF BUILDING ARRAYS OF WAVEGUIDE-HORN RADIATORS AND ANTENNA SYSTEMS Russian patent published in 2016 - IPC H01Q21/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to micro strip antennae, particularly to antenna systems. Disclosed is antenna system comprising: antenna array, which comprises rectangular dielectric substrate; multiple radiating panels arranged spaced along length of dielectric substrate on its upper surface; and multiple connecting panels on upper surface of dielectric substrate arranged in accordance with plurality of radiating panels, each of which extends from edge of dielectric substrate and ends at specified distance from corresponding radiating panel; and array of waveguide-horn radiators, which contains metal plate of rectangular shape, processed so that in cross section it contains multiple rectangular holes arranged along length of rectangular metal plate; wherein lower part of each hole is made in form of rectangular waveguide, and its top in form of horn; and groove of specified depth on both sides of holes on upper surface of rectangular metal plate, which stretches in direction of arrangement of multiple holes, each rectangular waveguide array waveguide-horn radiators is characterised by same size as corresponding radiating panel, and each rectangular waveguide is connected to corresponding radiating panel.

EFFECT: wider frequency range of antenna.
