Metamaterial lens and antenna

The invention discloses a meta-material lens and an antenna, the meta-material lens comprises a dielectric layer and a substrate layer, the dielectric layer comprises a plurality of transmission holes, and the plurality of transmission holes in the dielectric layer are arranged around the central point of the meta-material lens in an emission type annular manner. According to the metamaterial lens, the effective dielectric constant of the metamaterial lens medium is adjusted in the mode that the holes are formed in the metamaterial lens, and then the refractive index of the metamaterial lens is adjusted, so that the gain of the antenna provided with the metamaterial lens is improved. 本发明公开了一种超材料透镜与天线，所述超材料透镜包括介质层和衬底层，所述介质层包括若干个透射孔，所述介质层中的若干个透射孔围绕所述超材料透镜的中心点呈发射式环状排列。本发明通过在超材料透镜上穿孔的方式对超材料透镜介质的等效介电常数进行调整，进而调整超材料透镜的折射率，以此提高安装了所述超材料透镜的天线的增益。
