Abstract :
Coupled 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 backward coupling and interference between discrete reflections caused by termination mismatches at two ends.
