Efficient analysis of conformal antenna structures with multiple layers

Abstract

A systematic way to set up the dyadic Green’s function for multilayer structures using a full-wave equivalent circuit (FWEC) in curvilinear coordinate systems has been presented. The general formulation has been given in the first part of this contribution. Then, an application of the method has been shown for the case of a multilayered cylindrical microstrip line. The results, computed with the discrete mode matching method (DMM), have been validated with simulations done with Ansoft HFSS. The agreement between the simulations is very good, especially if the appropriate edge condition is used in the DMM formulation
