利用matlab控制3维仿真软件sonnet的工具箱，里面包含了详细的试用说明PDF，还有一个微带天线的例子，使得对天线的设计变得简单。

The program uses Sonnet or SonnetLite (the free version) to perform electromagnetic simulation on a probe fed, rectangular patch antenna. The design of the antenna is modified between Sonnet simulations. This design modification, simulation cycle is
