Abstract: Embodiments of the present disclosure provide a dual-polarized antenna. The dual-polarized antenna in the present disclosure includes two orthogonally arranged dipole units and a metal reflector. Each dipole unit includes two radiation arms and a balun structure, a preset angle is formed between the radiation arm and the balun structure, the radiation arm is connected to one end of the balun structure, and the metal reflector has a hollow-out structure. The metal reflector is disposed below the radiation arms, and the other end of the balun structure of each of the two dipole units passes through the hollow-out structure and is unconnected to the metal reflector. According to the embodiments of the present disclosure, antenna structure design is simplified, manufacturing processes are decreased, and a passive inter-modulation (PIM) risk is avoided.
