WAVEGUIDE BROAD-WALL LONGITUDINAL SLOT ARRAY AMTENNA FOR KA-BAND MONOPULSE RADAR MADE BY INTAGLIO TECHNIQUE

摘要

PURPOSE: A waveguide broad-wall longitudinal slot array antenna for a Ka-band monopulse radar made by an intaglio technique is provided to manufacture an aperture radiator, a feed plane, and a monopulse comparison surface using an intaglio technique. CONSTITUTION: A waveguide broad-wall longitudinal slot array antenna comprises an aperture radiator(100), a feed plane(200), and a comparison surface(300). The side is formed using an intaglio technique. The side is welded through a vacuum brazing technique. A radial slot side is made by the arrangement of a plurality of radial slots. The radiation-waveguide side transfers the electromagnetic wave energy to the plurality of radial slots.
