As the circuit density of pattern traces and the data rate on a printed circuit board (PCB) is increased, an unexpected electromagnetic interference (EMI) such as crosstalk can degrade the intended signal transmission. The crosstalk problems on multiconductor transmission lines (MTLs) which are parallel and have the same length have been researched by C. R. Paul[1]. In case of shifted parallel-...

A transmission line model is adopted for the analysis of slot-coupled microstrip reflectarrays. The current on the equivalent impedance for the single radiating element is used to obtain the reflectarray phase design curve. Computational costs are drastically reduced with respect to theoretical full-wave analysis. Numerical and experimental validations are presented on the phase curve useful fo...

ABSTRACT In this study, bifurcation and complex phenomena in synchronizing chaotic oscillators coupled by a lossless transmission line are investigated. The period-doubling bifurcation with varying the time delay is observed in our circuit model. Further the voltage distribution of transmission line is simulated in order to investigate whether the current flowing through the transmission line i...

The transmission line model for the single and coupled microstrip line components implemented in APLAC are presented. A detailed description of the algorithm used to calculate the characteristic impedance and the effective permittivity is given for the single microstrip, the symmetrical and asymmetrical pair of coupled microstrip lines, and the n symmetrical coupled microstrip lines. The effect...

A generalized two-way coupled-line power divider with extended ports for dual band is proposed in this paper. The power divider is composed of two section coupled-lines, one conventional transmission line, and an isolation resistor, and employs extension of a transmission line or coupled-line at each port. The design equations are obtained based on evenand odd-mode analysis, and analytical idea...

In this paper, we consider the finite element modeling of multilayer transmission lines for high-speed digital interconnects. We mainly focused on the modeling of the transmission structures with both cases of symmetric and asymmetric geometries. We specifically designed asymmetric coupled microstrips and four-line symmetric coupled microstrips with a two-layer substrate. We computed the capaci...
