Design and performance assessment of active phased arrays for communications satellites

摘要

This paper discusses the use of active phased arrays for communications satellite systems that require simultaneous multiple beams. The design of the complete phased array aims at satisfying the system requirements. The emphasis in the paper is on the evolution of the MMIC-driven highly modular technologies at Ku-, C- and X-bands. The paper reviews the designs of the different arrays in the development programs.
