The method of discontinuities analysis in microstrip-slotline structures. Part 1: Analysis of step discontinuity in microstrip line by transverse resonance technique
Abstract
The analysis algorithms of discontinuities in form of step discontinuity in microstrip line of finite length (inductive and capacitive discontinuities) by transverse resonance method was improved. For boundary value problems algebraization the irregular strip line current density is expressed through magnetic and electric vector potentials, representing the waveguide functions (orthogonal basis), which are obtained by solving the two-dimensional boundary value problem on its eigenfunctions and eigenvalues. The advantage of the proposed method consists in the fact that the order of truncation series in eigenfunctions remains constant in the analysis of discontinuity in a wide frequency range. The algorithms converge well and to ensure the accuracy of calculation of the resonance frequencies of the order of 10-2 (GHz), it is sufficient to consider two or three own eigenfunctions in the expansions of the electric and magnetic vector potentials for the current density.References
