Abstract :
Based on the quasi-TEM assumption, multiconductor transmission lines equations can be described by the multiconductor transmission line equations. In this paper, a fast frequency-domain method is proposed for the solution of the multiconductor transmission line equations, in which the finite element method is used to extract the circuit parameters from its cross-section and an algebraic matrix equation to describe its longitudinal propagation property. To verify its validity, this fast method is successfully used in the analysis of a microstrip bandpass filter.
