摘要
为使学生更好地理解微波天线辐射的基本原理及物理意义,提出将电磁场仿真软件HFSS应用到微波天线课程的教学中,使抽象难懂的天线理论公式转变为可视化的图形演示,提高学生的学习积极性,从而提升教学效果。以微带天线为例,采用HFSS仿真软件,对天线的反射系数、辐射方向图以及增益进行了分析和演示。实践证明,这种感性认知教学方法有助于加强学生对微波天线理论的理解和掌握。
In order to enable students to understand the basic principle and physical significance of the radiation of microwave antennas, the electromagnetic simulation software HFSS is applied in the teaching exploration of microwave antenna course, transforming the abstract antenna theory into visualized graphics demonstration, so as to improve the learning enthusiasm of students and the teaching effect. By taking microstrip antenna as an example, HFSS is used to analyze and demonstrate the antenna’s reflection coefficient, radiation pattern and gain. Practice has proved that this perceptual cognition teaching method is helpful for students to understand and master the theory of microwave antennas.
