Double-negative metamaterial characteristics are achieved through microstrip technology in a compact dielectric substrate at four different frequency bands of the minimal frequency ratio. The presented metamaterial is examined in two separate configurations of parallel and orthogonal feed. The circuit model of proposed metamaterial for both the cases is developed and projected in this paper. Moreover, the dispersion diagram and equations are originated to find out the dominant mode and zeroth-order frequency of realized metamaterial for both the feeding phenomena. Mathematical effective parameters (permittivity, permeability, impedance and refractive index) are extracted. Furthermore, a specimen of furnished metamaterial is manufactured to validate the mathematical and theoretical results.
