同轴矩形锥传输线的特性阻抗

The Characteristic Impedance of Rectangular-Coaxial-Cone Transmission Line

本文采用三维保角变换将矩形锤区域变换成柱域后求得了对称同轴矩形锥状传输线特性阻抗的上、下限值及用它们均值表示的传输线特性阻抗,为合理设计宽带横电磁波传输室(BTEM Cell)提供了理论依据。

The rectangular cone is mapped into a cylinder via conformal transformation in three dimensions. The maximum and the minimum values of characteristic impedance of a rectangular-coaxial-cone transmission line are obtained. The average of the two extreme values is in agreement with the characteristic impedance of the transmission line. The method enables one to design the characteristic impedance of BTEM cell accurately and easy.
