天线基本概念和原理实验教学设计与实现

Design and Implementation of Experimental Teaching for Basic Concepts and Principles of Antennas

针对教学中学生在理解天线基本概念和原理方面的困难,本文设计并实现了天线电参数测量实验。实验系统以矢量网络分析仪为基础,在微波暗室中搭建,具备天线方向图、增益和电压驻波比等参数测量功能。本文给出了系统配置和实验流程,并就如何基于天线测量系统开展相关教学工作进行了讨论。实践表明,实验教学是提高天线理论教学效果的有效手段。

Aimed at the difficulties that students usually meet when understanding basic concepts and principles of antenna, measurement experiments for electrical parameters of the antenna are designed and implemented. Based on a vector network analyzer, the system is carried out in a microwave chamber, with the measuring function of antenna azimuth pattern, gain as well as voltage standing wave ratio. Configuration and operating flow of the system are presented, and teaching based on measurement system is discussed. Practice proves that experimental teaching is useful means to improve teaching effect of knowledge about the antenna.
