摘　　要：介绍了用Ｍａｔｌａｂ语言编写的史密斯圆圈ＣＡＩ软件简单易用，具有用户图形界面，能绘出圆圈中任意曲线，能演示传输线输入阻抗随距离、频率变化所形成的轨迹以及单支节匹配等求解过程。同时，本文还利用该软件与计算相结合分析了同轴馈电矩形微带贴片天线的电特性，所得结果与有关文献吻合得很好。In this paper,CAI sotrware for Sheath Chart with Matlab language was presented, this software is simple and easy to use with user interface, it can not only draw arbitrary curves in the chart, but also demonstrate traces in which the input impedances of transmission lines change with distanes and frequencies and the solving processes for single-stub tuner. Moreover, by using the software and corresponding computations, the input impedances of probefeb rectangular microstrip antenna were computed. The numerical results are in good agreement with those provided by other papers.
