基于HFSS仿真软件的天线实验课程研究

Research on HFSS-based antenna experimental antenna teaching

针对目前高校在天线实验教学中实践环节开设不充分的问题,通过基于HFSS电磁仿真软件的对称振子天线和喇叭天线的仿真设计实例,提出采用HFSS仿真软件代替天线实物教学的实验课程改革,通过仿真得到天线的回波损耗、电压驻波比、输入阻抗及方向图,达到了节省设备资源、提高教学效果、调动学生兴趣的目的。该教学方法的实际教学效果表明,引入仿真实验对学生实践能力的提升起到了良好作用。

Aiming at the problem of inadequate state of practice link for antenna experimental teaching in the universities,this paper has shown the two experimental examples of the simulation of dipole antenna and horn antenna using HFSS software and proposed the adoption of electromagnetic simulation software instead of physical antenna in practical teaching link.The proposed teaching method can save equipment resources,improve teaching effects and arouse interests of the students.This teaching method has been carried out for more than two years and received the increasing praise of the students.The gained teaching effects have verified that the practical teaching method can significantly improve the practical ability of the students.
