| 摘 要： | 提出了一种宽带匹配网络设计的新思路。文中以任意输入阻抗的匹配为分析模型,详细分析了传输线在宽带匹配中的各种应用,并从宏观角度定性分析了传输线在阻抗匹配中的应用原理。在此基础上分析设计了一副工作在30～88 MHz频段、电压驻波比小于3．0的实用单极子天线,其实测结果良好地满足了要求。

| Abstract: | A novel method is proposed for designing broadband matching network in this paper.Applica- tions of transmission line in broadband matching are analyzed in this paper,based on the model of arbitrary im- pedance matching.Then the impedance matching theory of transmission line is studied qualitatively from the angle of macroscopic.In the end,a practical monopole antenna with the VSWR less than 3.0 in 30-88MHz frequency band is designed according to the analysis above,and the measurement results are in good agreement with the simulation results. |
