Abstract

Left handed meta atoms are special class materials that characterized by the negative refractive index. In this paper, a left handed biaxial meta-atom is reported that has 5.81 GHz wide bandwidth and applicable for C-, X-and Ku-band applications. The meta atom is developed by an outer and the inner split ring resonator with inverse E-shape metal strips of copper, which are connected with the outer ring resonator that look like a mirror-shape structure. A finite integration technique based CST Microwave Studio is utilized to design, simulation and analysis purposes, where the Agilent N5227A vector network analyzer is utilized for measurement purpose. Measurements show that, the measured and simulated results are well complied together and negative index bandwidth from 3.27 to 6.55 GHz (bandwidth of 3.28 GHz) and 7 to 12.81 GHz (bandwidth of 5.81 GHz) along the z-axis wave propagation. The total dimensions of the designed structure are 0.2×0.2×0.035 and the effective medium ratio 5, makes the proposed biaxial meta-atom is suitable for practical applications.
