The invention discloses a phase gradient metasurface antenna of a microstrip-line-like feed structure. The phase gradient metasurface antenna is composed of the microstrip-line-like feed structure and a radiating body of a phase gradient metasurface. The microstrip line feed structure comprises an SMA coaxial connector, a rectangular waveguide, a horn waveguide and a similar microstrip line; wherein the similar microstrip line is composed of an upper metal strip, a lower metal plate and a metal connecting band. The radiating body of the phase gradient metasurface comprises more than two metamaterial units, a dielectric substrate and a metal ground. The antenna profile can be reduced, a feasible scheme is provided for the design of a low-profile antenna needing to generate any radiation beam in 5G communication network application, and the phase gradient metasurface is used for adjusting and controlling the direction of a directional diagram, so that the defects that a parabolic antenna is large in size and the feeding of an array antenna is complex can be overcome, and the advantage of high degree of freedom can be achieved.
