The invention relates to a single-layer high-isolation dual-polarized antenna which comprises a dielectric substrate, a metal ground is arranged on one side of the dielectric substrate, a radiation patch is arranged on the other side of the dielectric substrate, a gap in a target shape is formed in the center position of the radiation patch, through holes are formed in the two sides of a feed port in the edge of the radiation patch, and the metal ground is arranged on the metal ground. The metal ground is provided with a through hole, the through hole extends to the metal ground to form a defected ground structure, a metal column is placed in the through hole, a feeder line is arranged above the metal column, and the feeder line is connected with the radiation patch below the metal ground through the metal column. After the continuous current band is introduced, the port isolation degree of the antenna is 7 dB higher than that of a traditional dual-polarization patch antenna, the coupling effect between two p
