Coupled lines perpendicular to their cylindrical ground plane embedded in a cylindrical structure are proposed and analyzed. CAD‐oriented analytic formulas for investigating the quasistatic mode parameters and the coupling properties are derived with the even–odd mode analysis method based on the quasi‐TEM approximation. Calculated mode impedances and coupling coefficients are observed to be sensitive to cylindrical curvature, especially for larger values of the spacing in the ground plane. Calculated results are compared with those obtained for a corresponding planar coupling structure. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 298–301, 1999.
