A dual-polarized antenna, including a radiating unit containing four conductive elements, four support elements, a feeding unit and a reflective plate, in which the four conductive elements are separated from each other by a cruciform slit at a middle of the radiating unit, top ends of the four support elements are connected to the conductive elements, and bottom ends of the four support elements are fixed on the reflective plate. The feeding element contains a PCB disposed at a middle of the radiating unit on top surfaces of the conductive elements and two coaxial cables disposed along the supporting elements and connected by its output conductors to a conductive layer covering a bottom surface of the PCB and connected by its input conductors to first ends of two strip lines disposed on a top surface of the PCB and forming two circuits matching the radiating unit with two coaxial cables.
