The satellites of the German National Program are two identical military communication systems providing SHF and UHF communication services. The paper will focus on the SHF antenna farm which was developed, manufactured and tested at EADS Astrium GmbH. After an outline of all antennas on the German National Program satellites, the qualification and RF performance of the SHF feed systems is presented...
For validation of RF pattern performance the modelling and simulation of complex antennas is an important step in the design process. The availability of efficient design tools and processing capacity of state-of-the-art computers allows an increasing high reliability on the calculation results. For higher frequencies above Ka-Band and mainly in the mm-wave frequency range, additional parameters and...
