Study of Characterization of a Micro-strip Line with Thick Copper Conductor Based on Iterative Method

In this work, two electromagnetic models are used for the characterization of a planar structure including a flat, thick copper conductor. Indeed the first model is consisted by modeling two metal ribbons without bulkiness, placed one above the other at a distance of h2 equal to the thickness of the thick conductor. This approach has been implemented and tested by the iterative method. The results of simulations have been compared with those calculated by the Ansoft HFSS software, and they are in good concordance, validating the method of analysis used. The second model is based on the calculation of the effective permittivity of the medium containing the thick conductor. This medium consists of a metallic region of complex relative permittivity ε′′ , the rest of this medium is filled with air εr2 = 1. The effective permittivity εeff calculated from these two relative permittivity εr2 and ε′′. Comparing the simulation results of this new formulation of the iterative method with those calculated by the software Ansoft HFSS shows that they are in good matching which validates the second model.
