The frequency hopping characteristics of the proposed MTM is investigated by open and short-circuited the three outer rings split gaps by using three switches. The MTM offers a high effective medium ratio (EMR) of 15.1, indicating the design's compactness. The array performance of the MTM is also evaluated by using 2 × 2, 4 × 4, and 8 × 8 arrays that show close resemblance with the unit cell. The simulated S 21 of the MTM unit cell is compared with the measured one and both show close similarity. The equivalent circuit is designed and modeled in Advanced Design System (ADS) software. It shows negative permittivity, near-zero permeability, and near-zero refractive index in the vicinity of these resonances. The MTM provides four major resonances of transmission coefficient (S 21) at 2.48, 4.28, 9.36, and 13.7 GHz covering S, C, X, and Ku bands. The unit cell of proposed MTM is initiated on a low-cost FR4 substrate of 1.5 mm thick and electrical dimension of 0.06λ × 0.06λ, where wavelength, λ is calculated at the lowest resonance frequency (2.48 GHz). The meander line helps to increase the electrical length of the rings and provides strong multiple resonances within a small dimension. The metamaterial unit cell is a modification of the conventional square split-ring resonator in which the meander line concept is utilized.

#2.4 GHZ METAMATERIAL CST MICROWAVE STUDIO VERIFICATION#
Different array structures have been designed and analyzed for the verification of DNG characteristics. Effect of different parts of the unit cell on resonance characteristics has also been alluded. Commercially available finite difference time domain (FDTD)-based computer simulation technology (CST) has been used for designing the unit cell. Moreover, the unit cell has realized a compact size of 0.792 cm 2, which is the smallest reported size with the DNG bandwidth more than 4 GHz in a particular band. Combination of rectangular split ring resonator and complementary H-shaped resonator has been used to construct the unit cell. A modified H-shaped double negative (DNG) metamaterial unit cell aimed at X- and Ku-band applications has been presented.
