“…Using the method of lines, a microstrip line with finite metal thickness and finite conductivity shown in Figure 1 has been analyzed with the following parameters: The effects of finite metallisation And a comparison also has been done with the theoretical data given in Ke and Chen (1995), which shows a reasonable agreement. From the results, we note that the effective dielectric constant and the attenuation constant of microstrip lines increase as the thickness of the strip decreases.…”

“…This method (Kollipara and Tripathi, 1992) is confined to the case of infinite thin strips and considers the thick strip as two current sheet at its top and bottom. And then the spectral domain method has been expanded (Ke and Chen, 1995), but when using the Galerkin's method to get the eigen function, basis functions are hard to choose and the calculations of integrations (Fourier transform, inverse Fourier transform and Galerkin's method) need much time. The method of lines (Pregla, 2008) is also an effective method to analyzing the planar transmission lines with finite thickness lossy strips (Schmuckle and Pregla, 1990).…”

Purpose -The purpose of this paper is to study and discuss the effects of the finite metallisation thickness and conductivity on the properties of microstrip lines. Design/methodology/approach -Effective dielectric constant and attenuation constant of microstrip lines with finite metallization thickness and finite conductivity are analyzed by the method of lines. The experimental results are obtained by using Vector Network Analyzer and the 3680 V Universal Test Fixture of Anritsu. Findings -The strip thickness has a great impact on the attenuation constant of the microstrip lines. The effects can be divided into three parts by the relationship between strip thickness (t) and skindepth (d). When t , d, the attenuation constant will decrease rapidly as the strip thickness increase. When d , t , 2d, the attenuation constant still decrease rapidly as the strip thickness increase, but the slope of the curve will be smaller. When 2d , t, the effects of the strip thickness will become insignificant and the attenuation constant still decrease slowly as the strip thickness increase. Originality/value -This paper presents some useful principles about the effects of the finite metallization thickness and finite conductivity in microstrip lines. The reasons for these effects are discussed by analyzing the longitudinal electric field distribution in the strip. Finally, some experimental results are given to verify these principles.

“…With the dimensions of monolithic integrated microwave circuits (MMICs) decreasing, some electromagnetic effects that were ignored by many previous analyses have received increasing attentions, such as finite metallization thickness [1] and conductor losses [2]. And at high frequencies, the conductor losses of composite-metal microstrip lines should also be considered carefully for a highly accurate model.…”

SUMMARYA full-wave analysis of the composite-metal microstrip lines is presented. The effects of the composite metal to the loss of the microstrip lines are accurately investigated, which are often avoided by other methods. The metal layers of the microstrip lines are considered as lossy inhomogeneous layers. The effects of the thickness of the Au layer and Ti layer are given, respectively. And the reasons that lead to the differences between them are discussed for the first time by analyzing the longitudinal electric field on the strip. The results are compared with other published data.

“…For large thickness (t), the model converges to a surface impedance as in the IBC approximation and for t → 0 it converges to a shunt resistance as in the R-card model. In [37], all three components of strip currents were considered in the modified SDA. The rigorous integral equation formulation with dyadic Green's function was proposed for the skin effect of conductor strips [38].…”
