Finally, the curve of the relation between input and load impedance of the exponential waveguide is given and discussed. 最後，討論了指數形波導管的阻抗特性，分析了輸入阻抗與負載阻抗之間的關係。
The radiation and impedance characteristic of microstrip antenna may be influenced by cutting slots on the groundplane with applications to widening the frequency band. 接地板開槽可以改變微帶天線的輻射特性及阻抗特性，在微帶貼片天線的頻帶展寬中已有所應用。
