Abstract
This paper reveals the design and analysis of a new split-H-shaped metamaterial unit cell structure that is applicable for multi-band frequency range, and it shows negative permeability and permittivity at those frequency bands. In the basic design, the two separate split square resonators have been added by a metal link to form H-shape unit structure. Moreover, the analyses and comparison of the 1 × 1-array, 2 × 2-array structures and 1 × 1, 2 × 2 unit cell configurations have been investigated. All these configurations demonstrate its multi-band operating frequency (S-band, C-band, X-band, K u -band) with double negative characteristics. The equivalent circuit model for the unit cell is presented to demonstrate the validation of the resonant behavior. The commercially available finite-difference time-domain based simulation software CST microwave studio has been used to get the reflection and transmission parameters of the unit cell. In summation, the material also exhibits single negative characteristics in the multi-band frequency range if it is projected on the 20 × 20 mm2 substrates. The simplicity, scalability, double negative characteristics, and multi-band operations have made this design novel in the electromagnetic paradigm.
