摘要：
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 degrees, 0 degrees), (32 degrees, 90 degrees), (32 degrees, 180 degrees), (32 degrees, 270 degrees). 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 degrees similar to 22 degrees, 90 degrees similar to 112 degrees, 180 degrees similar to 202 degrees, 270 degrees similar to 292 degrees, respectively.
