Antenna for the reception of circularly polarized electromagnetic waves radiated from a broadcasting satellite

摘要

The antenna which is suitable for individual or community antenna installations has a reflector (2) for the reception of circularly polarised electromagnetic waves, radiating from broadcasting satellites, especially in the 12 GHz band, the reflector (2) having the shape of an asymmetrical section of a paraboloid. A primary emitter (6) is aligned on the reflector (2), arranged on the axis of symmetry (4) of the paraboloid predominantly outside the secondary radiation field of the reflector (2). IMAGE
