However, because of the variety of microstrip line, the plicate mathematical model, and the tedious calculation process, in those condition, this tool brings a lot of difficulties in the practical application. The paper is mitted to programming, which can realize the plex calculation formula of the microstrip line, and we use graphical user interface(GUI) which is a manmathine friendly software. GUI has many elements, such as window, cursor, menu and so on. When selecting and clicking these elements , we can finish many function easily, which is called what you see is what you get, so this characteristic is a good application, especially in the graphics. GUI is the first choice for the software that will be published, and its interface design quality determines the future of software on the market. In order to develop a microstrip line calculator, in this paper, we will use mathematical modeling to analysis the structure of the microstrip line, and design program with GUI tools in Matlab software. In addition, GUI will be translated through the plier into a software that can run independently, so that we can use this calculator software to analysis and integrated design in microstrip line circuit, which can improve the efficiency of the circuit design and reduce the workload of calculation.
