Abstract (en)
[origin: EP0034809A1] 1. A micro-wave directional antenna, for the production of a sector-shaped radiation lobe, consisting of a reflector having an oval aperture and a radiator made of a non-rotation-symmetrical waveguide (9) on whose inner wall is fixed a dielectric insert (10 à 13) projecting over an opening in the waveguide, which radiator thus emits radiation mainly emanating from a ring zone running around the longitudinal axis of the radiator so as to be non-rotation-symmetrical, characterized in that the waveguide (9) possesses a rectangular cross-section, and that the dielectric insert comprises dielectric plates (10 to 13) fixed on each of the four inner walls of the waveguide.
