A method of realizing multiband and broadband left-handed metamaterials with low-loss is presented. By integrating oblique triangular open-loop pair resonator plus wire (OTOR-wire) with oblique triangular open-loop pair resonator (OTOR), the combined structure exhibits double LH passbands, which can form broad LH passband by adjusting the unit cell geometrical dimension. Simulation and experimental results and analysis demonstrate that this structure exhibits negative effective permittivity and permeability simultaneously in a frequency range from 9.3 GHz to 13.2 GHz, its relative negative refraction passband reaches 347%, and the figure of merit reaches 347.9. The idea can help us to design multiband and broadband left-handed metamaterials with low-loss
