带状线传输线类似于标准带状线传输线,但具有圆形导体。建模近似可用于了解带状线传输线的阻抗。

The wire stripline transmission line is similar to a standard stripline transmission line, but with a round conductor. Modeling approximation can be used to understand the impedance of the wire stripline transmission line.

 

Description

带状线由悬挂在两个接地层之间的圆形导体构成。导体和接地层用电介质隔开。该计算器假定两个参考平面之间的距离相等。

A wire stripline is constructed with a round conductor suspended between two ground planes. The conductor and ground planes are separated with a dielectric. This calculator assumes the distance between the two reference planes to be an equal distance.

 

Microstrip Transmission Line Models

传输线的阻抗 Z 0 由直径为 d 且以相隔距离 h 的平行接地平面为中心的圆形信号导体组成,由下式给出:

The impedance Z0 of a transmission line consisting of a circular signal conductor having a diameter d and centered between parallel ground planes separated by a distance h is given by:

 

  Eq. 1

 

Impedance calculation

Microstrip impedance shall be calculated according to above Eq. 1.
