| 摘 要： | 提出了一种预测网状可展开天线电性能的数值计算方法.针对网状可展开天线采用三角形拼合的这一特点，首先从结构力学出发确定天线枕效应变形，然后采用巴斯卡图插值进行面片网格划分，给出了网格划分准则，其次通过最佳吻合抛物面确定最优馈源的位置和指向，最后考虑丝网的电磁漏射对网状天线进行电性能预测.通过仿真算例验证了该方法的可行性和有效性.

| Abstract: | A numerical method for electromagnetic(EM)performance prediction for mesh deployable antennas considering pillow deformation is proposed in this article.Accounting for the characteristics of mesh reflecting surface which is faceted by a series of triangles,the amount of pillow deformation is computed firstly based on the antenna structural parameters;Secondly,with the Pascal graph interpolation,the meshing of the surface facet is accomplished with a given criterion;The position and orientation of the optimized feed are both obtained using the traditional best-fit paraboloid(BFP)method;Finally,the EM performance is predicted under the influence of wire mesh leakage.Simulation results of a mesh deployable reflector validate the feasibility and effectiveness of the method. |
