The present invention discloses a dual-polarized antenna, which comprises a first antenna element and a second antenna element which are crossed with each other. The surface radiating units of the first antenna element and the second antenna element are arranged on the upper face of a first PCB substrate; the bottom radiating surfaces are arranged on the bottom face of a second PCB substrate. The first PCB substrate, the second PCB substrate, the surface radiating units and the bottom radiating units are all connected via through-holes. Inner layer feeder lines are disposed between the first PCB substrate and the second PCB substrate. The bottom ends of the surface radiating units are provided with surface layer feeder lines and matched circuits, wherein the matched circuits are connected with the first PCB substrate. The bottom end of the first PCB substrate is provided with feeder line through holes. The bottom ends of the first antenna element and the second antenna element are both connected with a coaxial radio frequency connector. The inner layer feeder lines are connected with the feeder line through holes; and the feeder line through holes are connected with the matched circuits. The matched circuits are connected with the surface layer feeder lines; and the surface layer feeder lines are connected with the inner core of the coaxial radio frequency connector. The dual polarized antenna of the invention generates ultra-wide-band signal radiation, which realizes the high orientation and miniaturization.
