Abstract
Conference Title: 2016 19th International Conference on Computer and Information Technology (ICCIT) Conference Start Date: 2016, Dec. 18 Conference End Date: 2016, Dec. 20 Conference Location: Dhaka, Bangladesh In this paper, a new multiband metamaterial structure designed and simulated of unit-cell that has multiple hexagonal concentric metal rings one inside the other. The each ring of metamaterial structure delivers a magnetic resonance at different frequencies. The number of concentric ring resonator has created number of resonances. In this study, different analysis has been performed to verify distinct resonance frequencies, effective medium ratio and electromagnetic transmission properties simply by altering the design parameters. Computer Simulation Technology (CST) electromagnetic simulator which is commercially available is utilized to investigate the design of the metamaterial. The multiband response has been displayed of the metamaterial in conjunction with negative index material property over the certain span in the microwave regime. The proposed structure has become suitable for S-band, C-band, X-band and Ku-band applications and has achieved efficient electrically small microwave structure.
