Evaluation of Array Fed Reflector Architectures for Broadband Satellite Missions

In this paper, an efficient tool to estimate the antenna system performance of Array Fed Reflector configurations is presented. Acceleration techniques are applied to the analysis of the reflector antenna to estimate the beam patterns. Then, some system parameters are evaluated once the channel characteristics are fully defined. Finally, a parametric study of the multibeam coverage is shown as an example of the capabilities of the tool. The final aim of the study is the optimization of the antenna payload in terms of system parameters such as the aggregated throughput.
