| Abstract: | A novel planar transmission-line style of left-handed metamaterial is proposed, and its electromagnetic characteristics are investigated. The dispersion curve of the proposed structure has been derived by using Bloch-Floquet theory and the CRLH TL is proved. Then the equivalent circuit model of the CRLH TL unit is provided, the parameters of the equivalent circuit model are extracted under balanced and unbalanced conditions by optimizing and synthesizing. The model is validated by comparing the circuit result with the simulator result. The novel planar transmission-line style of the left-handed metamaterial does not need defected ground structure, so it can be easily designed and fabricated. |
