[ 摘 要 ] 随着电磁场理论及计算电磁学的发展，各种电磁场数值计算方法已经广泛应用于电磁场工程设

计中。经过多年的发展与完善，商业化电磁仿真软件如ANSOFT HFSS的计算精度与效率不

断提高，成为工程设计中必不可少的工具。仿真软件HFSS向用户提供了用户开发工具，可

以实现自动化、批处理建模仿真，并能够对仿真数据做后处理。编写了一个基于HFSS脚本

语言的程序。利用该程序，对一个对数周期偶极子天线的进行了建模和仿真。仿真结果显示满

足设计要求。

[ Abstract ] With the development of the EM theory and CEM, lots of numerical algorithms have been

used in EM engineering. After rapid development in recent decades, commercial EM

software as ANSOFT HFSS have higher accuracy and efficiency, and become necessary

tools in EM engineering. HFSS also provide with a build-in User Programmable platform. It

can do the modeling and simulation task automatically and in batches. It can do post

processing as well. A program based on the HFSS scripting is developed. Modeling and

simulation of A log-periodic dipole antenna are performed using this program. The simulated

result shows that it is fit for the requirement.

[ Keyword ] HFSS; User Programmable platform; log-periodic dipole antenna

1 前言

目前，仿真软件ANSOFT HFSS的计算精度和效率不断提高。但是要建某些阵列天线或其他复杂函数线构成的天线，操作工作量会增大，检查错误和修改模型都较困难。HFSS提供了基于VBScript的宏命令来进行软件的二次开发。采用HFSS的VBscript宏能方便模型的建立和修改，提高工作效率。通过VBScript可以建立HFSS仿真模型，也可控制HFSS包括材料设置、边界设置、激励设置、求解设置等所有操作。
