Numerical simulation of the proposed design is executed in CST microwave studio. These tuning metal strips are acted as spacers between four quartiles of the resonator patch. The quartiles are connected at the center of the substrate with a square metal strip with which four tuning metal strips are attached. The symmetric resonating patch is subdivided into four equal and similar quartiles with two interconnecting split rings in each quartile. The proposed metamaterial is constituted on a Rogers (RT-5880) substrate with 1.57 mm thickness and the electrical dimension of 0.14λ × 0.14λ, where wavelength, λ is calculated at 4.2 GHz. In this paper, a tuned metamaterial (MTM) consisting of a symmetric split ring resonator is presented that exhibits epsilon negative (ENG), near zero permeability and refractive index properties for multiband microwave applications.
