Design and analysis of a novel concentric rings based crossed lines single negative metamaterial structure
چکیده انگلیسی
This paper presents the design and analysis of a novel single negative metamaterial (MTM) based on concentric rings with crossed lines (CR-CL) to be miniaturized to λ/4 at 15G Hz. The unit cell is structured to behave as a single negative MTM, -ε or -μ, at different frequency bands. The unit cell is consistent of a dielectric substrate, 5 × 5 × 1 mm3, of FR4-Epoxy underneath of a conductive patch designed as 4.4 × 4.4 mm2. A complete analysis in terms of S-parameters, constitutive parameters and refraction index are evaluated for the unit cell using both full wave simulation and circuitry analysis as well. Nevertheless, the unit cell characteristics based circuit equivalent lumped components are retrieved. HFSS software package based on Finite Element Method (FEM) and Advanced Design System (ADS) based on circuit analysis formulations are invoked to perform the simulation study. Later on, the obtained simulation results are compared to their identical measurements based on transmission line technique. Finally, the simulated and measured results are agreed excellently.
