The purpose of this article is the analysis and design of a new bandpass metamaterial filter structure, the analysis of this filter is made by applying the concept of ground plane demetallization. The resonator used for the demetallization is a spiral-shaped split ring metamaterial resonator, this resonator which represents a negative permeability (μ<0), has a magnetic resonance. It allows a qualitative control of the bandwidth of the global filter; it also increases the level of electromagnetic coupling with the microstrip lines. The feed lines used at the input and output of the microwave filter have coplanar access adapted to 50 Ω. Numerical calculations are carried out based on the High Frequency Structure Simulator (HFSS) for the finite element method (FEM). The obtained results show a dual-band band-pass DBBPF behavior for two central frequencies located at the C- and X- bands, which nominates the filter to be a potential candidate for wireless communications applications.
