摘要高频结构电磁场仿真软件( High Frequency Structure Simulator，HFSS) 是开发于20世纪60年代的用于微波器件进行三维仿真的软件。天线设计的时候大多数情况下都会使用它。当然，单靠HFSS也是不能满足所有设计要求的，它在优化设计方面也是有缺陷的，比如在进行对复杂的设计对象进行仿真时就不是那么可靠了，如果我们想利用优化算法进行优化，我们就可以利用编程接口程序来实现，在使用过程中我们往往通过MATLAB来进行脚本的编写。矩阵实验室（Matrix Laboratory，MATLAB）不仅具有简单易读易写的功能，还可以进行复杂的计算以及三维建模。HFSS在开发时考虑到这方面需求，所以HFSS是可以调用vbs脚本进行模型的建立的，正是由于两软件接口程序的存在，我们可以利用MATLAB弥补HFSS建模的不足，通过联合仿真的方式来设计那些高要求的天线。64872

该文主要介绍了使用联合仿真的技术，完成对200MHZ半波偶极子天线的设计。通过对半波偶极子天线的设计分析详细说明联合仿真的可行性和优越性，为更为复杂的天线设计打下基础，相信这种仿真模式也会受大众欢迎。

Abstract

High frequency structure electromagnetic simulation software (HFSS) is a 3D microwave simulation software in the nineteen sixties, has greatly promoted the development of microwave engineering application is extremely broad, especially in antenna design and simulation application.By HFSS alone we can't meet all the design requirements because of its lack of optimization function, when the optimization design is a complex object, it is not so reliable, so when we want to use optimization algorithm for optimization, we can use programming interface to implementation. Under normal circumstances we use vb language files to record scripts, while MATLAB scripts can be used to read and write.MATLAB not only has the simple language, easy to read and write, it also has a complete scientific computing and modeling function. the HFSS software with the use of vbs script language modeling function, it is precisely because the two software interface program, we can use MATLAB to make up for lack of HFSS modeling.we can use it to do united simulation for the design of complex antenna, or device to do a quick modeling.

This paper describes the use of the interface, complete the script on the design of the 200MHZ half-wave dipole the half wave dipole antenna design detail joint simulation analysis of the feasibility and superiority, and lay the foundation for more sophisticated antenna design. I believe that this simulation model will be popular.
