The multi-band structures have the advantage of providing the same electronic function for different frequency bands and for a single compact circuit. In this paper, a new metamaterial resonator was modeled for multi-band applications. The proposed structure is a non-periodic split-ring resonator of H-C shape (HC-SRR). The copper patch of the HC-SRR is printed on the upper side of the used dielectric substrate which is Rogers RO 4003 of physical characteristics (εr = 3.55 and tgδ = 0.0027). The electrical dimensions of the HC-SRR unit cell are optimized at (0.374λ0 x 0.362λ0 x 0.039λ0), where λ0 is the free space wavelength calculated at the lowest operating frequency which is 7.25 GHz. The HC-SRR is modeled based on its equivalent electrical circuit containing the (LS – CS) series branches. The obtained results show a dual-band bandpass behavior of our metamaterial resonator at both resonances of 7.25 and 9.31 GHz. This behavior was validated by the equivalent circuit model based on the reflection characteristic. Other physical characteristics of the proposed resonator are obtained such as constitutive parameters and electric field to show the unusual electromagnetic behavior of the proposed HC-SSR. Obtained negative values of permittivity and/or permeability can define the left hand medium (LHM) represented by our resonator. The study and analysis proposed in this work can justify the impact and efficiency of the proposed HC-SRR for multiband applications, especially for wireless communication devices. |
