Abstract

In this paper, a new optimization design method for wide-area shaped multi-beam antenna is proposed. The performance of the antenna is improved by the shape optimization of the reflective surface, and the high gain and high C/I performance of the wide-area covered shaped multi-beam antenna is achieved. In the optimization, the reflector expansion coefficient is taken as the variable, and the objective function is constructed by the antenna gain and C/I. Then the differential evolution algorithm is used for optimization to obtain the best performance. The simulation results show the effectiveness of the algorithm, and the optimization algorithm also takes the engineering realizability of the product into full consideration. The measured results show that the product has better performance than the design requirements, the antenna has been launched with the satellite, and the in-orbit test and application are good.
