Abstract
In this paper, a new high-gain antenna with beam control based on multilayer non-uniform metasurfaces (MNMSs) is proposed. The MNMS consists of multilayer non-uniform square and ring metal patches array. The phase-shift of the MNMS element can achieve 310° with the variation of geometrical sizes. Moreover, four high-gain antennas based on MNMS element are designed, fabricated, and measured to realize 0°, 30°, 45°, and 60° beam control in pitching plane, respectively. Relative bandwidth of the proposed high-gain antenna is above 12%. The simulated and measured results of the proposed antennas show that the wide-angle and azimuth direction beam control capability can be effectively realized by integrating different MNMS with the feeding horn antenna.
