摘要
在天线理论与技术课程教学中,天线的基本概念和工作原理较为复杂抽象,且天线的实验验证及性能测试依赖价格昂贵的微波测试仪器及微波暗室等条件,尤其是高增益天线由于其电尺寸较大、仿真难度也较大。针对课程现存的这些教学难点,介绍了CST微波工作室在高增益天线设计实验教学中的应用。以一个24 GHz高增益反射阵天线为教学案例,通过软件的应用使学生掌握天线手动建模、VB宏语言自动化建模、2D/3D天线方向图查看、天线辐射效率计算等教学内容。同理论教学相比,基于CST微波工作室的实验教学环节可有效地将天线设计过程形象化、案例化,使得“天线理论与技术”课程教学更具说服力,提高课程的教学效果和专业水平。
The basic concept and working principle of the antenna are usually very complex.Meanwhile,the performance measurement and experimental verification of the antenna need expensive microwave measurement instruments and microwave anechoic chambers.In particular,the simulation of the high-gain antenna is difficult due to its large electrical size.In view of these difficulties in the course of antenna theory and techniques,this paper describes the application of CST Microwave Studio in the experimental course of high-gain reflective array antenna design.Through taking the design of a 24 GHz high-gain reflective array antenna as an experimental case,the students could have a good grasp of manual antenna modeling,automatic antenna modeling using VB macro language,and vividly view antenna pattern and master antenna radiation efficiency calculation.Compared with the theoretical teaching,the experimental course based on the CST Microwave Studio can effectively makes the teaching more convincing.It could improve the teaching efficiency and professional level of the course of antenna theory and techniques.
