Abstract
Metamaterial is an innovation that makes today's world look forward to another research area extension. In this proposed article, a double negative multi-split based square split ring resonator is discussed, where the Rogers- RT 5880 is used as a dielectric medium. The metallic design is composed of copper material printed on the dielectric substrate. The resonant frequencies are located from 2.5 to 2.6, 4.4–5.0, 8.3–9.0, 10.3–12.3, 14.0–14.5 and 15.3–15.7 GHz. This unit cell shows negative values of effective permittivity, effective permeability, and refractive index. The design is observed with the electric field and magnetic field distribution with vector field representation and analyses with various rotation angles on the XZ plane, different substrate material, and the minimisation of the dimension.
