HFSS在角锥天线仿真中的应用

例题：角锥喇叭建模尺寸 5.16in0.315in Air box Horn Antenna Horn一、创建工程第一步：打开HFSS并保存新工程打开HFSS 软件后，自动创建一个新工程：Project1。由主菜单选File\Save ，保存在指定的文件夹内，命名为horn。一、创建工程第二步：插入HFSS设计由主菜单选Project\ Insert HFSS Design，则一个新项目自动加入到工程树中，默认名HFSSModel1。同时，在工程树的右侧出现绘图窗口。在工程树中选择HFSSModel1，点右键，选择Rename项，将设计命名为HornModel。一、创建工程第三步：选择求解类型由主菜单选HFSS\Solution Type ，在弹出对话窗选择 Driven Model 一、创建工程第四步：设置单位：由主菜单选3D Modeler\Units ，在Set Model Units 对话框中选中in Boxicon followingvalues -0.2, -0.45, 0.4,0.9, 0.315 dx,dy, dz,respectively otherwords, itscenter. 二、创建模型 HornType Base namefield.
