可视化天线阵教学软件的开发与应用

Development and Application of Visual Antenna Array Teaching Software

天线阵是“天线”课程中的一项重要内容,其理论复杂、抽象,初学者不易掌握。文章基于谢昆诺夫单位圆开发了一款天线阵的可视化分析与综合软件。利用该软件可以通过输入和调节阵因子零点的位置观察副瓣电平、主瓣宽度等参数及方向性图的变化规律,并能同时给出相应的单元激励电流幅度比,因此既可以用于天线阵的分析,也可以用于天线阵的综合。整个过程可视,具有直观、简捷、高效、易于理解和掌握的特点,且可用于实现天线阵的个性化设计。

Antenna array is an important part in Antenna course,its theory is complex,abstract,and it's hard to master for beginners.In this paper,a visual analysis and synthesis software of antenna array is developed based on Schelkunoff unit circle.The software can be used to observe the variations of sidelobe level,main lobe width and directional pattern by inputting and adjusting the positions of zero points of array factor,and the corresponding excitation current amplitude ratio of antenna elements can be given at the same time,so it can be used not only for the analysis of antenna array,but also for the synthesis of antenna array.The whole process is visible,with the characteristics of intuitional,simple,high efficient,easy to understand and master,and can be used to realize the individualized design of antenna array.
