This paper introduces a new planar microstrip metamaterial resonator, the novelty of this paper lays in its unit cell design. The unit cell is formed by connecting metallic traces of two edge coupled split ring resonators to form the infinity symbol on one side of the substrate, and an array of conducting wires on the other. An RLC equivalent model of the structure is also proposed, it can be advantageous to use this model to identify the resonant frequency along with the root of the negative permeability and negative permittivity. The model shows resonance at 17 GHz. The structure was designed and simulated using EM solver Ansys HFSS, the extracted s-parameter matrix was analyzed to determine the effective permittivity, permeability and index of refraction. The structure shows negative values for effective ε, µ at resonant frequency 16.5 GHz. At frequencies where both the recovered real parts of ε and µ are simultaneously negative, the real part of the index of refraction is also found to be negative.
Key words: Microstrip metamaterial, negative refraction, permittivity, permeability, RLC circuit.
