一种低成本圆极化天线实验教学的研究

Research on low cost circularly polarized antenna experimental teaching

为全面提高学生对天线特性(包括阻抗特性、方向特性和极化特性)的理解,使学生亲身体验天线从设计制作到测试应用的全过程,提出了一种适合实验教学的低成本圆极化天线结构,并给出了工程化的天线实验教学思路。实验过程包括理论设计、软件仿真、天线制作、测试调试和工程应用等环节。通过一系列的训练,使学生熟悉天线电磁仿真软件、掌握天线参数分析和测量的方法,培养学生创新设计天线的能力。

In order to improve students＇ understanding on antenna characteristics （including input impedance, radiation pattern and polarization）, and to enable students to experience the whole process from antenna theoretical design to the engineering application, a low cost circularly polarized antenna structure suitable for experimental teaching has been proposed. The experimental teaching idea of antenna engineering has been put forward, including theory design, simulation, fabrication, measurement and engineering application. Through a series of training, the students can be familiar with electromagnetic simulation software and master the antenna parameters analysis and the measurement method. It can ultimately achieve the objective to cultivate the students＇ innovative ability in antenna design.
