Abstract
The left-handed materials(LHM) are widely used in antenna, filter and other microwave devices due to its negative permittivity and negative permeability. This paper proposed a new kind of left-hand materials, by means of equivalent circuit analysis, electromagnetic simulation, and extract the equivalent electrical parameters, the results show that the structure realized double negative features in the 9.3 GHz to 14.2 GHz. At the same time, the real part of the equivalent negative refractive index is negative and the imaginary part is approximately to zero. The structure has the characteristics of low loss, wide frequency band and the technology is simple. It provides reference for the design of LHMs in microwave filed.
