摘要
本文采用Fourier变换的方法,给出了分析套筒天线的通用程序;系统研究了各参变量对天线阻抗特性的影响并给出了相应的曲线。在此基础上,总结出一种行之有效的理论设计和实验调整方法并利用此法设计了实用的工作于40MHz~88MHz的套筒天线。理论结果与实验测试相吻合。
In this paper,the pourier transformation method is used to analyze a sleeve monopole antenna and a general program is given. Our goal is to study the characteristics of the impedance of the sleeve monopole with different parameters over a broad frequency range. Therefore,many corresponding curves are also provided here. Thus,we are able to vary five parameters so as to alter the impedance of the sleeve monopole easily. On the basis of these results,a sleeve monopole antenna in the range 40MHz-88MHz with VSWR<3. 0 is designed. Theoretical results derived here agree well with experimental data. The conclusion made can be widely adopted in concerned antenna experiments and designs.
