A method of designing a single side left-handed structure based on the integration of electric resonator and magnetic resonator is proposed in this paper. The left-handed units are composed of two cross types of metal mirrors that are parallel-placed on the same side of the substrate and then arranged into a periodic structure. The results of HFSS software simulation and a series of effective electromagnetic parameters extraction show that the left-handed structure exhibits negative effective permittivity and permeability simultaneously in a frequency range from 9.4 GHz to 16 GHz. Its relative passband reaches 52%, and the unit electrical length and loss are less than those of the same type of structures. The periodic structure is fabricated and tested using the waveguide method. The fine left-handed feature is proved again. This new structure lays a foundation for the wide applications of left-handed metamaterials.
