SMALL-SIZE WIDEBAND WAVEGUIDE-HORN ANTENNA AND ANTENNA ARRAY STRUCTURE BASED THEREON Russian patent published in 2013 - IPC H01Q13/00 

FIELD: radio engineering, communication.

SUBSTANCE: wideband horn antenna array has an open waveguide, having a radiating end and a tail end, top and bottom conducting crests inside the waveguide; behind the tail part of the waveguide there is a conducting frame; between the tail part of the bottom crest and the back wall of the frame there is a gap; waveguide and tail parts of the crests facing each other are parallel to the base. In the back wall of the frame opposite the end face of the tail part of the bottom crest there is an opening for entry of the centre conductor of a communication cable with a transceiver through an insulator. A cable shield is mounted on the back wall of the frame and has electrical contact with the back wall. The concave part of the crest lies near the radiating end of the waveguide and the convex part of the crest connects the end of the crest on the base with the concave part. The antenna array has columns in which horns are spaced apart by a distance close to half the minimum signal wavelength.

EFFECT: reduced weight and size characteristics of the wideband waveguide horn, enabling operation thereof as part of antenna arrays.
