The present disclosure provides an antenna packaging structure radiating e-m waves in a horizontal direction and a vertical direction and a method making the same. The method includes: providing a support substrate, forming a separation layer on a surface of the support substrate; forming a rewiring layer on the separation layer; forming an antenna array layer on the rewiring layer, the antenna array layer is electrically connected to the metal wire layer; the antenna array layer includes first antennas and second antennas arranged in an array respectively, radiating e-m waves in the horizontal direction and the vertical direction respectively; forming a molding material layer; removing the support substrate and the separation layer; forming solder ball bumps on a surface of the rewiring layer away from the antenna array layer, the solder ball bumps are electrically connected to the metal wire layer; disposing a chip on the solder ball bumps.
