Description
Summary:The aim of this article was to design CSRRs (complementary split ring resonator) miniaturized metamaterial cells. These cells should then be associated with planar microwave devices to achieve microwave filters. First, we focused on the design and electromagnetic simulation of metamaterial including CSRR and rod metal. Simulations are performed using HFSS software based on the finite element method. For each cell, we presented the transmission and reflection coefficients obtained using this software. The second part is dedicated to the design of bandpass filter based on CSRRs. This filter contains a CSRR cavity and two metal stubs, designed to operate around 7 GHz. In order to obtain a powerful filter, we study the influence of the physical dimensions of the structure on the frequency response. This filter provided good performance in terms of bandwidth and adaptation.
