Design of Metamaterial-Based Bandstop Filters Using Complementary Split Ring Resonators

  • Hany A. Atallah


In this study, a miniaturized metamaterial bandstop filter (BSF) based on complementary split ring resonators (CSRRs) is presented. The filter is constructed on low dielectric constant substrate, which combines the conventional filter characteristics and the negative permittivity properties of the metamaterials to establish a metamaterial filter. The negative permittivity metamaterial is produced by CSRRs, which are etched in the ground plane. Two and three CSRR unit cells are cascaded in a periodic manner to design a high performance BSF. The frequency characteristics of the proposed filters are successfully designed and optimized using numerical experimentation techniques. The major parameters affect the filter performance is being investigated. The results show that the compact SBF has an insertion loss less than 0.5 dB and easily adjustable rejection bands of about 3.2 and 4.6 GHz widths using cascaded CSRRs cells periodic structures. Simulation results based on a 3D full-wave EM simulator are presented in this paper.
