Abstract：A novel resonant-type composite right/left-handed transmission line and its correlative lumped-element equivalent circuit model are presented based on regular hexagon complementary single split ring resonator pair.The effective mechanism of its transmission lines is further defined,the control of the reso-nance frequency and that of the transmission band are realized through analysis of the structure parame-ters.A perfect balanced condition at 4 GHz is accomplished for the novel CRLH TL,and its impedance bandwidth comes to 1.85 GHz (3.61~5.46 GHz),and the relative bandwidth comes to 40.8%.The circuit model is analyzsed in depth by adopting transfer parameter matrix and Bloch-Floquet theory.A high coinci-dence of parameters'results of the circuit model and the electromagnetic simulation proves the correctness and efficiency of the circuit model.And a balanced condition is extracted.The negative refractive index and the backward wave propagation are demonstrated by the effective electromagnetic parameter retrieval.
