A planar discontinuous transmission line feed structure of a phase gradient metasurface antenna disclosed by the present invention is characterized in that a microstrip line, a metal strip, a metal layer and a phase gradient metasurface are all arranged at the top of a dielectric substrate, the microstrip line is fixedly connected with one end of the metal strip, the metal layer is fixedly connected with the other end of the metal strip, and the metal layer is fixedly connected with the dielectric substrate. The four rows of phase gradient metasurfaces are evenly and symmetrically distributed on the two sides of the metal strip, and the metal ground is fixedly connected with the dielectric substrate and located at the bottom of the dielectric substrate. The phase gradient metasurfaces of the same structure and number are placed on the two sides of the metal layer, the phase gradient metasurfaces are excited through energy radiated by coupling of the metal layer, and the phase gradient direction is designed al
