摘要
设计了电磁场与波课程中进行天线教学的一项创新实验。以电磁波综合实验仪为平台,设计了适合天线测量实验的转台和接收指示装置,替代价格昂贵的微波接收和发射设备。通过对如何开展八木天线为例进行分析,对实验方法进行了详细设计。实验结果表明,测试精度可以达到天线教学实验要求。该项新实验已连续两年在本科生教学中应用,明显起到了提升课程教学效果和学生实践能力的作用。
An innovative experiment of antenna teaching is presented in the course of Electromagnetic Fields and Waves.Taking electromagnetic waves comprehensive experimental instrument as a platform,one designs antenna measurements installations of turntable and receipt of instructions to replace expensive microwave receiving and transmitting equipment.By analyzing the Yagi antenna,one elaborates the experiment.The results that the accuracy of test required to achieve antenna teaching experiment.The new experiment has been teached for two years in undergraduate applications,which significantly improves teaching effectiveness and students＇ practical ability.
