In this study, the capacitances of strip transmission lines of various thicknesses and widths were accurately calculated using the mode-matching method. To perform the mode-matching method, a strip transmission line structure was modeled, and the potential for the analysis space was expressed by applying the Laplace equation and the principle of superposition. Dirichlet and Neumann boundary conditions were applied to calculate the mode coefficient included in the derived potential expression. Additionally, to verify the validity of the mode-matching analysis, the convergence of the potential for a specific location was confirmed, and the analysis results of the mode-matching method and commercial simulation were compared. Using the verified mode-matching analysis, the change in capacitance according to the thickness and width changes of the strip transmission line was investigated, the capacitance was calculated using the approximate equation, and bar bridging and analysis were performed. From the analysis results, the capacitances calculated using the approximation formula differed depending on the structure of the strip transmission line. The structure of the strip transmission line that needed to be calculated by rigorous electromagnetic analysis was confirmed. This differs from a previous study in that the mode-matching analysis can precisely predict the capacitance corresponding to the geometrical variation of the strip transmission lines.
