Finally, the curve of the relation between input and load impedance of the exponential waveguide is given and discussed. 最后，讨论了指数形波导管的阻抗特性，分析了输入阻抗与负载阻抗之间的关系。
The radiation and impedance characteristic of microstrip antenna may be influenced by cutting slots on the groundplane with applications to widening the frequency band. 接地板开槽可以改变微带天线的辐射特性及阻抗特性，在微带贴片天线的频带展宽中已有所应用。
