用于计算微波集成电路传输特性的横切面谐振散射模型理论

本文将介绍,适用于目前较为实用的微波集成电路(MIC)各种传输结构的,横切面谐振技术的散射模型方程。通过使用反射系数矩阵来表示边界条件,该方程可算出无金属衬底、有金属衬底、屏蔽的微带线,槽线,及共面波导的传输特性。在基模和高次模的情况下,经计算所得传输特性与理论数据相比,是非常相符的。与其它模型的计算方法相比,该方程的计算软件不必在计算机主机上运行,只需在386型微机上进行运算即可。

A Scattering-Type Transverse Resonance Technique for the Calculation of(M)MIC Transmission Line Characteristics

A scattering-type formulation of the transverse resonance technique is introduced and applied to a variety of currently practical (M)MIC congurations. By utilizing a reflection coefncient matrix representation of boundary conditions, the characteristics of open, conductorbacked and shielded microstrip, slotline,or eoplanar waveguide can be calculated. Excellent agreement with measurements and theoretical data on fundamental and higher-order mode characteristics is obtained. In contrast to other methods, which require mainframe srpport, the software based on this formulation is operational on 386-compatible personal computers.
