摘要
利用边界元法计算了内圆外矩同轴传输线的特性阻抗。这种方法计算量小,适用面广,精度也满足工程需求。计算结果和文献的数据非常接近。文章给出了一些曲线和表格,为合理选择内圆外矩同轴线的尺寸结构提供了参考。
A numerical method, Boundary Element Method, is introduced to calculate the characteristic impedance of a rectangle coaxial line with round center conductor. It has many advantages of small calculating amount, widely applied aspects and high accuracy. Many curves and forms are given in the text.
