An Analysis of Multistrip Line Configuration on Elliptical Cylinder

A configuration of multistrip lines mounted on a multilayer dielectric-coated elliptic cylinder is investigated in this paper. A full-wave analysis and a moment-method calculation are employed. The analysis is carried out considering the expansion of the field as a series of Mathieu functions. Both open and shielded lines are considered in the analysis. Propagation coefficients and characteristic impedances are calculated for the lines with different ellipticity. The results are verified by comparing them with those obtained from commercial software.
