计算鳍线特性阻抗的新公式

A New Formula for Finline Characteristic Impedance Calculating

通过采用更为合理的鳍加载波导模型取代[1]中选用的脊波导模型,本文得到了改进的计算鳍线特性阻抗的新公式,该公式在上下鳍不对称的一般情况下也能使用。计算结果与严格数值解及测量值吻合很好。

By using a more reasonable fin-loaded waveguide model instead of the ridged waveguide model used in[1], a improved new formula for calculating finline characteristic impedance is presented in this paper. The new formula is usable for the general unsymmetrical fin-loaded cases. Results calculated here are in good agreement with exact numerical solutions and experimental data.
