Zusammenfassung:	In this paper, a multi-beam antenna based on metasurface is proposed. By employing the metasurface as radiating element, steering the beam in the elevation plane is realized. Also, the substrate placing above the metasurface helps to further improve the beam performance. The results indicate that the realized the antenna radiate four beam pointing at (\theta , \phi) = (32°, 0°), (32°, 90°), (32°, 180°), (32°, 270°). Based on this, by adjusting the feeding network, beam is steered in azimuth plane. When the length of the left patch decrease from 11.95 mm to 10.45 mm, the azimuth angle of four beams can be adjustable between 0° ~22°, 90° ~112°, 180° ~202°, 270° ~292°, respectively.
