Quasi-TEM Study of Coplanar Waveguide with Step Microshield

摘要: 提出了一类新型共面传输线用于MMIC的设计,该类共面传输线为梯形屏蔽共面波导(SMCPW)。导出了用于计算该传输线的TEM参数的解析公式,其方法是基于传输TEM模假设,用精确的保角变换实现的,最后得到的数值结果显示了该类共面传输线的性质。

Abstract: A new configuration of coplanar transmission lines is discussed,including step microshield coplanar waveguide(SMCPW).The simple,analysis and practical formulas for the evaluation of the quasi -TEM characteristic parameters is presented,which is based on a conformal mapping procedure.The results show the characteristics of these new transmission lines.
