Asymmetric coupled transmission lines with anisotropic coupling
IEEE International Digest on Microwave Symposium, 2002The characteristics of asymmetric coupled transmission lines are derived for the case of general anisotropic coupling, special cases of which are certain geometries of anisotropic materials or from distributed active devices. In addition to deriving the terminal characteristics for the uniform coupled-line, four-port case with anisotropic coupling, it ...

Transmission Line Theory for Field-to-Transmission Line Coupling Calculations
Electromagnetics, 1988The paper discusses basic principles and validity limits of the field-to-transmission line coupling calculating using Transmission Line (TL) theory. Attention is given to the EMP-power lines interaction. A review of the fundamental equations and method of solution is given, considering that two equivalent formulations are possible.

Conical Coupled Stripline Transmission Lines
2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2006A new structure is proposed to use as an interconnect in the VLSI circuits. This structure has a shield and some strip lines all in conical form. After describing the full-wave formulation, the approximate transmission-line analysis of the structure is presented. The properties of the structure are studied using an example.

Coupling between microstrip transmission lines
1995 International Conference on Electromagnetic Interference and Compatibility (INCEMIC), 2002The finite difference time domain (FDTD) method is applied to predict the coupling between coplanar microstrip transmission lines. Calculated values of coupling coefficients are found to be in good agreement with the measured data.

Coupled transmission lines revisited
IEEE Transactions on Education, 1988The author presents a very satisfying and disarmingly simple way of introducing students to the parallel line coupler, which derives its S matrix directly from a knowledge of its eigenvectors and eigenvalues. For a pair of symmetrical coupled lines, the eigenvectors can be found by inspection, and the eigenvalues determined easily by means of flow ...

Synthesis of coupled transmission lines
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1997In this paper an important property of the time responses of coupled transmission lines is proven. Based on this property coupled transmission lines are synthesized from the given near-end and far-end time-domain responses. The inductance matrix L and capacitance matrix C of uniformly coupled lossless lines can be obtained from the responses without ...

Coupled-Transmission-Line Directional Couplers
IEEE Transactions on Microwave Theory and Techniques, 1958Formulas are presented for the design of coupled-transmission-line directional couplers that are rigorous for any value of coupling. Two basic types are treated in detail; the simplest is one-quarter wavelength long at the center of its frequency band, while the other is three-quarter wavelength long.

Slit-Coupled Strip Transmission Lines
IEEE Transactions on Microwave Theory and Techniques, 1966Two types of slit-coupled strip-line configuration are presented which are especially useful for the realization of multi-section components using printed-circuit techniques. The slit-coupled configurations described consist of a pair of strips oriented face to face and either parallel or perpendicular to the outer ground planes.

Analysis of nonuniform coupled transmission lines using generalized transmission line equations
2005 Asia-Pacific Microwave Conference Proceedings, 2005In this paper, a new analysis for nonuniform coupled transmission lines is presented using 2D generalized transmission line equations (GTLE). To simplify the computation, the decouple procedure is adopted. And then 2D-GTLE are transformed to 1D-GTLE. 2D-GTLE have broad band characteristic.

Bi-directional coupling between two coupled transmission lines
IEEE Microwave and Wireless Components Letters, 2003Coupled mode theory including backward coupling is employed to investigate the bi-directional coupling mechanism in two symmetrical coupled microstrip transmission lines. Analytical scattering parameter expressions for the case of matched terminations are presented. Reflections and near-end crosstalk is attributed to the combined effects of distributed
