Title Research on EMC Simulation of Whole-Satellite
Abstract In recent years, satellite products present some characteristics such as high degree of electronic equipment integration, working frequency band of the system continue to be broken, great transmission power, high sensitivity of receiving equipment and large number of antenna。 Electromagnetic compatibility problems of whole-satellite have become more and more prominent。 In this paper, we use the coupling degree and radiation pattern as the objective functions, optimize the layout of the dipole antenna。 The optimization procedure based on the HFSS-Matlab-Api scripts and Matlab genetic algorithm toolbox, and in particular use the parallel process of genetic algorithm to improve the computing ability。 Finally, we compare the optimal solution of the algorithm with the theoretical value, verify the accuracy and feasibility of the genetic algorithm in optimization of the antenna layout。 This achieves the completion of whole-satellite EMC design during the design phase。 It has an important significance in the optimum design of satellite products。
