摘要：

In this paper, a transmission type negative refractive index metamaterial surface acting as a planer surface lens is presented. A measured 3 dB transmission band of 2 GHz from 8.55 GHz to 10.55 GHz is obtained. Material property of the proposed meta-surface is extracted by using free space technique. The designed meta-surface is radiation beam conversing in nature. Aperture efficiency of the designed meta-surface is 84.30 %. A high gain antenna is designed by placing the proposed double stacked meta-surface lens over a micostrip patch antenna operating at 10.06 GHz. A gain enhancement of 8.55 dB in H-Plane and 6.20 dB in E-Plane at resonating frequency 10 GHz is obtained. The cross polarization level is improved by 8 dB.
