The invention relates to a printed broadband low-profile omnidirectional dual polarization antenna, belonging to the radio technical field. The present invention solves the problem that the section height of the prior broadband omnidirectional dual polarization antenna is high. The invention comprises a vertical polarization unit, horizontal polarization unit, Plastic screw, vertical feeding portand horizontal feeding port, four plastic screws fixedly connected with vertical polarization unit and horizontal polarization unit, the distance between vertical polarization unit and horizontal polarization unit is 37mm, vertical feeding port is fixedly installed on vertical polarization unit, horizontal feeding port is fixedly installed on horizontal polarization unit. A vertical polarization unit and a horizontal polarization unit of the present invention are independent antenna structures and are respectively fed by a vertical feeding port and a horizontal feeding port, vertically polarized element antennas are mainly composed of two layers of dielectric substrate and radiator printed on it. Because of the introduction of dielectric substrate, the section height of vertical polarizedelement antennas is effectively reduced.
