Abstract (en)
[origin: EP1109245A2] The antenna has a parabolic reflector, a stimulator acting as a sub-reflector and a radio box on the rear of the reflector connected via a hollow conductor to a transmitter/receiver. A polarization switch (8) arranged between the radio box and hollow conductor for simultaneous transmission of two orthogonal linearly polarized waves has two hollow conductor paths (9,10), one straight and one with a 90 degree bend.
