The invention discloses a metasurface loaded high-gain differential patch antenna, belongs to the technical field of metamaterial antennas, and solves the problem that the metamaterial antenna is low in aperture efficiency and gain when radiating electric wave signals. A metasurface array is arranged above the dielectric substrate in parallel, the center lines of the metasurface array in the x-axis direction and the y-axis direction coincide with the center lines of the dielectric substrate in the x-axis direction and the y-axis direction respectively, the metasurface units form the metasurface array with N columns and N rows, and each metasurface unit comprises a supporting medium and a copper-clad ring; the copper-clad rings are symmetrically arranged on the front surface and the back surface of the supporting medium, and the center lines of the copper-clad rings in the x-axis direction and the y-axis direction coincide with the center lines of the metasurface units in the x-axis direction and the y-axis di
