The purpose of this article is the analysis and design of a new structure of the bandpass filter, the analysis of the composite structure is made from a bandpass filter using microstrip resonators connected in parallel that are associated with a circular Split Rings Resonators metamaterials present a negative permeability (SRR) to create an environment of retro-propagation of waves. The behavior of the composite filter is also bandpass but around the resonance frequency of (SRR), which is

RR), which is inferior to the center frequency of the first band-pass filter, which allows a good operation of the composite filter in the stop-band of the first bandpass filter with resonators coupled in parallel. Since there's no scientific or experimental result in the literature for this kind of complicated structure, it was necessary to perform simulations using CST MICROWAVE STUDIO.
