Abstract (en)
[origin: EP0817311A2] The antenna energising system has a dielectric radiator (3) at the end of a hollow waveguide (2), for the electromagnetic waves, positioned centrally relative to the parabolic reflector (1). This is provided with a metallised end face acting as a sub-reflector. The parabolic reflector is formed from several rectangular metal strips, the end face of the radiator being provided by two opposing pairs of partial surfaces (8,9,10,11), on either side of the central axis. The partial surfaces, in the direction of the main axis (A) of the reflector, are larger than the partial surfaces in the perpendicular direction.
