An Analysis of elliptical-rectangular patch structure on multilayer elliptic cylinders

The resonance frequency problem of an ellipticalrectangular patch mounted on multilayered dielectric coated elliptic conducting cylinder, is investigated in this paper. A fullwave 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. An additional theorem for Mathieu functions is utilized to investigate the non-confocal ellipse case. The complex resonance frequencies for the structures with double layer substrate and structure with superstrate layer are calculated.
