A Numerical Study on Electrical Characteristics of Large Deployable Reflector Antennas with Phased Array Feed

摘要

In the electrical study of large deployable reflector antennas with phased array feeds, the relationship between the performance of feed equipment and the radiation characteristics has not been investigated. To achieve the optimum satellite antenna system, this paper describes the electrical characteristics, which include a relationship between the antenna gain and beam direction when a dynamic range of excitation amplitude is constrained and the reduction of antenna gain related to the malfunction of amplifiers.
