A rigorous analysis of uniform stripline of arbitrary dimensions

A rigorous and computationally efficient analysis for stripline of arbitrary dimensions based on the transverse resonance diffraction technique is presented. Calculated higher-order-mode cutoff frequencies show excellent agreement, and the calculated attenuation factor shows good agreement with measured values for an air-filled stripline. The calculated values are more accurate than predictions from numerical or analytical techniques for a wide range of dimensional ratios. With the approach considered here, considerably less time is required to compute the data, and the algorithm can be programmed on a desktop computer
