摘要/Abstract

摘要： 给出了电基本阵子天线的场分布,无方向性天线远场辐射功率与天线尺寸的关系,且基于Ansoft HFSS（High Fre-quency Structure Simulator）绘出2款半波阵子天线,给出天线输入端口1处电压反射系数分贝表示dB（S（1,1））及辐射平面图,可简单验证辐射效果与天线工作频率或波长的关系,同时增强学生对天线辐射及电参数的感性认识,改善教学效果.

Abstract: The radiation field of electric dipole the far field radiation power of non-directional antenna and relationship between power and dimension secondly are presented.Two half wave antennas with different dimensions are compared based on Ansoft HFSS,S11 of return loss and far field pattern are changed with frequency or wavelength,the relationship between radiation and antenna operating frequency or wavelength are tested further.Practices show that these perceptual knowledge enhance the quality of teaching and obtain satisfied teaching effects partly.

Key words: high frequency structure simulator, D＇Alembert＇s equations, radiation power, return loss
