PHASED-OUT HORN Russian patent published in 1995 - IPC

FIELD: antenna equipment. SUBSTANCE: phased-out horn includes horn with flare angle 22α₁ and wide-angle horn with flare angle 22α₂,, α₂ being bigger than α₁, and impedance extension which radius is chosen by certain selection. Phased-out horn makes it possible to improve axial symmetry of main lobe within wide range of frequencies in specified sector of angles while maintaining good matching with feeding path of phased-out horn with fracture of generating line (conical or pyramidal). EFFECT: improved axial symmetry. 2 dwg
