Abstract :
This work presents the analysis of quasi-square open ring frequency selective surface, FSS, using the Wave Concept Iterative Procedure, WCIP. As this structure presents a strongly dependence of the electric field polarization, different frequency bands can be selected. Furthermore, there is a coupled strips region and its length can be used for frequency adjustment. The behavior of the electric fields and how it can affect the resonant frequency is discussed. Numerical and measured results for the frequency of resonance are compared and a good agreement is observed.
