摘要
针对电磁场理论辐射部分的教学困难,文中先分析电基本振子的辐射特性,然后引入半波偶极子天线的HFSS仿真结果,给出了回波损耗曲线,辐射方向图等形象直观的结果。与理论部分的公式和概念相结合分析,给予学生清晰、立体的认识,提升了教学效果。
To solve the teaching difficulties of radiation field in electromagnetic field theory course, firstly the electric dipole characters are analyzed, the simulation result of the half-wave antenna based on Ansoft HFSS is applied in paper, gives the image and directly results of return loss and radiation pattern. Combined analysis of the formula and concept of radiation theory,help students make deeper understanding and improve the teaching efforts.
