| Sumario: | The parametric analysis used in the determination of effects of parameters, both geometrical and associated to dielectric in Frequency Selective Surfaces (FSS) constitutes a method of widespread use as a result of the scarcity of formulations for the assessment of this type of effects. The objective of this method of analysis is to determine the influence in resonant frequency of a particular parameter, either associated to the dielectric support or to the geometrical parameters of the selective surface, in order to guide the process of design of the surface. This article presents the application of the Equivalent Circuit Model (ECM) acting in conjunction with an innovative formulation of the effective permittivity of the dielectric in square loop FSS, that enables the determination of the geometrical parameters and those associated to the dielectric on resonant frequency of the selective surface. The proposed methodology makes unnecessary the use of analysis of parametric type. The results obtained show an acceptable accuracy in comparison with the electromagnetic simulations performed in software based on Finite Element Method (FEM). |
