The invention presents a multi-beam dual-mirror antenna based on a meta-surface. The characteristics of polarization selection and multi-beam radiation are realized simultaneously, and the structure of the antenna is simplified. The multi-beam dual-mirror antenna comprises a primary mirror, a feed source, a secondary mirror and a support structure. The primary mirror adopts a hollowed-out planar array structure composed of polarization conversion meta-surface elements, each of which comprises a first dielectric substrate, a double-opening ring metal patch printed on one side of the first dielectric substrate and a metal floor on the other side. The secondary mirror adopts a planar array structure composed of polarization selection meta-surface elements, each of which comprises a second dielectric substrate, a single-opening ring metal patch printed on one side of the second dielectric substrate and a metal grid on the other side. The primary mirror is divided into multiple rectangularareas, and the adjacent rectangular areas have an additional phase difference of 180 degrees, so that multiple radiation beams in different directions are obtained.
