The invention discloses a near-field focusing planar array antenna which is high in efficiency, small in size and low in cost. The near-field focusing planar array antenna comprises a first copper-coated metal layer, a first medium layer, a second copper-coated metal layer, a second medium layer, a third copper-coated metal layer, a third medium layer, a fourth copper-coated metal layer, a fourth medium layer and a fifth copper-coated metal layer, wherein the first copper-coated metal layer, the first medium layer, the second copper-coated metal layer, the second medium layer, the third copper-coated metal layer, the third medium layer, the fourth copper-coated metal layer, the fourth medium layer and the fifth copper-coated metal layer are sequentially laminated from top to bottom. Metallized radiation holes are formed in the first medium layer. Metallized phase shift holes are formed in the second medium layer. Metallized transition holes are formed in the third medium layer. A substrate-integrated waveguide parallel feed network is arranged on the fourth medium layer. According to the near-field focusing planar array antenna, phase compensation is achieved through the metallized phase shift holes, the compensation range is wide, the structure is simple, performance is excellent, efficiency of the antenna is high, the size of the antenna can be greatly reduced, and cost can be reduced; in addition, different focusing positions can be adjusted. The near-field focusing planar array antenna is suitable for being popularized and applied in the technical field of microwave antennas and millimeter wave antennas.
