This paper details the extraction of two possible equivalent circuits over a wide band for an mm-Wave Electric-LC resonator on a multilayer stack, based on a T structure or on only one shunt susceptance with two transmission lines. An identification process applied to the frequency behavior of the reactance/susceptance is used to obtain a more appropriate and efficient equivalent circuit, giving a physical meaning, if any, to each inductance, capacitance or resonator tank contained in the proposed circuits.
