  • Publication number: 20090160718
    Abstract: A plane focus antenna includes a plurality of stacking substrates. Each substrate has one side formed a periodic array plane consisting of a plurality of resonant coils and other side laid a metal wire formed in a periodic structure. The magnetic permeability of the stacking double split-ring resonators is negative and the electric permittivity of the metal wire is negative at the same time that can interact with electromagnetic waves to fabricate a negative refractive index material (NRIM) to form the plane focus antenna. By means of the special refractive effect of the NRIM receiving signals can be converged in a very small area to enhance the receiving signals. The plane antenna also does not generate distortion.
