Abstract
In this paper, a left-handed metamaterial is proposed for multiband applications analysed by azimuthal (xy-plane) angular (φ) rotations. The square resonators are split and a metal bar titled in a way that look like a z-shape split ring resonator structure that is angular sensitive. The metamaterial is designed on the epoxy resin fibre substrate material, which shows extended bandwidth approximately 47.5% of the applicable frequency from 2.0 to 14.0 GHz and the quality factor is 77.30. Finite integration technique based electromagnetic simulator computer simulation technology Microwave Studio is used to design, simulation, and analyses purposes. The demonstrate structure rotates from 0° to and every degree intervals in the xy-plane for analysing the effects on bandwidths, effective medium ratio and left-handed characteristics. However, the measured data are well complied with the simulated data by rotating the metamaterial at the above mentioned azimuthal angle.
