Abstract (en)
[origin: WO9213373A1] The antenna system according to the invention includes a lens (11), which focusses incoming waves (10) at respective focal points (12a-c). Helical feeders (23a-c), which are provided near said focal points (12a-c) and preferably integrated in said lens (11), receive the waves (10) and appropriate signals are led by feeder lines (14a-c) to a suitable receiver (15). By the antenna system according to the invention a mechanical support for the feeders and the feeder lines can be provided. If a hemispherical lens is used, the antenna system is less bulky and especially in this case the length of required feeder lines can be reduced and the receiving efficiency can be increased. The system according to the invention is preferably used as part of a system for receiving Direct Broadcasting Satellite microwaves from different satellites.
