Ansoft HFSS在微波技术与天线教学实践中的应用

摘要

在微波技术与天线课程的教学过程中,由于数学公式复杂、场结构难以观察,给学生学习带来一定困难.该文利用电磁结构分析软件Ansoft HFSS对矩形波导中的TE10模、电基本振子的辐射场、天线二元阵的方向图进行仿真求解,以可视化方式展示场结构与方向图.理论分析与仿真实验相结合,加深学生对课程基础知识的理解.%In the teaching process of microwave technology and antennas, some difficulties for students may lie in the complex mathematical formulas and invisible electromagnetic ifelds. To address the problem, the TE10 mode of a rectangular waveguide, the radiation ifeld of an electric short dipole and the ifeld pattern of a two element array were analyzed and graphically represented by Ansoft HFSS in this paper. The combination of theory and simulation could add students' understanding to the basics of the course.
