The aim of this paper is to describe a split S-shaped composite meta atom which shows double negative characteristics at resonance frequency. The proposed meta-atom structure exhibits an almost 3.70 GHz bandwidth when the operating frequency from 8 to 14 GHz (X-band). In this study, the ring width, split width, size of substrate material, and the substrate material itself are varying to investigate their effect on the resonance frequencies. Metal strips of the outer resonator are the splits and the inner ring resonator is designed in a way that it forms a split S-shaped structure on the epoxy resin fibre (FR-4) substrate material. The CST Microwave Studio electromagnetic simulator software was used for the design and simulation purposes, and an Agilent N5227A vector network analyser was used for practical measurements.

In this paper, an effective medium ratio obeying, negative refractive index, compact meta-atom was designed, manufactured and tested for operation in a multiband microwave regime. The proposed meta-atom structure obeyed better effective medium ratio. The results of the measurement were verified by the commercially available Computer Simulation Technology (CST) Studio Suite 2014 simulator. The effective medium ratio obeying meta-atom displayed multiband response, in conjunction with negative refractive index property over a certain frequency band in the microwave frequency span. Furthermore, a few parametric analyses were completed with the meta-atom, and the effective medium parameters were investigated. The sizes and complex scattering constitutive parameters of the proposed negative refractive index, compact meta-atom are applicable for multiband applications in microwave regime.
