1. This method is using two times conformal transformation method and mirror theory to calculate the characteristic impedance.
   这种方法是采用两次保角变换结合同轴线特性阻抗公式进行特性阻抗计算。
2. Through conformal mapping, the calculation method of its characteristic impedance the impedance is derived by converting the convoluted strip line into an asymmetric one.
   通过保角变换将其特性阻抗的计算转化为对非对称型平板带状线特性阻抗的计算，并得出了卷绕型带状线特性阻抗的计算方法。
