Abstract—In this paper, a wide beam scanning high gain compact metasurface lens antenna for 5th generation mobile communication system operating at 28 GHz using a wide band transparent linear graded index metasurface lens is designed. First, a highly transmissive metamaterial unit cell with wide 3 dB transmission band of more than 10 GHz transmission bandwidth with maximum resonance at 27.5 GHz is designed. A graded index metasurface lens is designed by using modulated modified double circular ring resonator unit cell. The designed lens causes a gain enhancement of 5 dB in the broad side direction by placing over a microwave radiator operating at 28 GHz. The mechanical movement of linear graded index metasurface lens results in to wide beam steering in a conical plane of apex angle 60° with stable gain variation in the direction of + 30° to - 30° with maximum gain of 11.5 dBi and reduced side lobe levels.
