西德广播卫星的天线系统是由西德进行系统设计及元部件制作的。主承包商是MBB公司。系统的构思及设计是以世界无线电行政大会(WARC)77/79年会所提出的要求为依据的。设计的关键是要压缩天线边瓣辐射的共极化信号及压缩在地球视场内的正交极化信号。本天线系统的主要任务是:
The antenna system of the West German broadcasting satellite is made by West Germany for system design and component production. The main contractor is MBB. The concept and design of the system was based on the request of the 77/79 WARC. The key to the design is to compress the co-polarized signals radiated by the antenna side lobes and compress the orthogonally polarized signals in the Earth’s field of view. The main tasks of this antenna system are:
