Abstract
This study proposed an interlinked coupled split square ring resonator (SSRR) based metamaterial (MTM) unit cell. The double-negative (DNG) metamaterial characteristics are exhibited in C, X, and Ku microwave frequency bands. The proposed MTM unit cell contains six split square ring resonators (SSRR) where a horizontal metal bar is interlinked between the fourth and fifth SSRR and a vertical metal bar interlinks between the third and fifth SSRR. The perfect electric conductor (PEC) and Rogers- RT 5880 are used in the resonator and dielectric layer to design the MTM unit cell. The unit cell has a dimension of 10×10×1.57 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> , and the thickness of the resonator layer and dielectric layer is 0.04 mm, 1.57 mm, respectively. The Computer Simulation Technology (CST Microwave Studio 2019) software is used to extract effective parameters then the finite element method (FEM) is used to verify the unit cell’s performance. Due to symmetrical structure, negative permittivity, negative permeability, and negative refractive are achieved. As a result, the proposed unit cell can improve microwave devices’ performance for C, X, and Ku bands, particularly satellite and radar communications.
