微屏蔽传输线的分析与计算

Analysis and Calculation of the Microshield Line

微屏蔽线(MSL)是一种新型的平面传输线,其超高的频率响应和极低的色散特性,可望广泛地应用于各种毫米波电路中。本文把用于鳍线、微带线的谱域导抗法推广到这种半封闭的传输线中,分析、计算了两种微屏蔽传输线的色散特性。计算结果与有关的实验相吻合,为这种半封闭的新型毫米波传输线提供了一种有效的计算方法。

Mieroshield hne(MSL) is a new type of monolithic planar transmission line which will be widely used in millimeter circuit for its ultra-high frequency response and very low dispersion. The spectral domain impedance approach is extended to calculate this half-closed transmission line. The results of calculation agree well with the relevant experiments, which provides an effective method for calculating the MSL.
