WAVEGUIDE-SLOT ANTENNA EXCITER Russian patent published in 1995 - IPC

FIELD: antenna equipment. SUBSTANCE: first version of waveguide-slot antenna exciter has section of rectangular waveguide which one end carries matched load, first, second and third pairs of conductive plates, first and second systems of radiators, two current conductive plates perpendicular to first and second pairs of parallel conductive plates which are placed at angle smaller than 90 deg relative to plane of corresponding side walls of rectangular waveguide. First and second systems of radiators are displaced with reference to longitudinal axes of corresponding wide walls of rectangular waveguide and their projection on to plane passing across longitudinal axis of rectangular waveguide and in parallel to its wide walls in symmetry to this axis. Description of invention gives two more versions of make of wave-guide-slot antenna exciter. EFFECT: expanded operational field. 9 cl, 10 dwg
