First Claim
1. A planar meta-material comprising:
- a planar dielectric material having a single layer structure with single permittivity or a multilayer structure having at least two permittivities;
a first conductor unit, which is disposed on a top surface of the planar dielectric material and comprises a first conductor having a loop shape; and
a second conductor unit, which is disposed on a bottom surface of the planar dielectric material and comprises a second conductor having the same shape as the first conductor,wherein the permittivity, permeability, and refractive index of the planar-meta material have values of 0-1 or a negative value in a predetermined frequency domain.

Abstract
Provided is a planar meta-material (100) having negative permittivity, negative permeability, and a negative refractive index through a simple structure using a general conductor and a dielectric material (130), a planar meta-material structure including a planar meta-material (100), and a lens realized by using the planar meta-material structure or an antenna system, which has high efficiency and high gain, by including the planar meta-material structure. The planar meta-material includes: a planar dielectric material (130) having a single layer structure with single permittivity or a multilayer structure having at least two permittivities; a first conductor unit (110), which is disposed on a top surface of the planar dielectric material and includes a first conductor (110a, 110b) having a loop shape; and a second conductor unit (120), which is disposed on bottom surface of the planar dielectric material and includes a second conductor (120a, 120b) having the same shape as the first conductor, wherein permittivity, permeability, and a refractive index of the planar meta-material have zero or a negative value in a predetermined frequency domain.
