Dual-polarized antenna

The invention discloses a dual-polarized antenna, and the antenna comprises a grounding layer and two feed-in arms. The grounding layer comprises a central vacant part, an external frame part surrounding the central vacant part, an isolation segment which extends towards the center of the central vacant part from the external frame part, and two gaps which pass through the external frame part from the central vacant part. A hypothetical online inclined angle of an extending direction of each gap from the central vacant part to the outside is less than 180 degrees. Each feed-in arm comprises a radiation part, a main arm part which is connected with the radiation part and is located in one gap, and a feed-in part which is connected to one end, far from the radiation part, of the main arm part. The two feed-in arms are employed for exciting different polarization in two directions, and are enabled to cause no impact on each other through the isolation segment, thereby achieving good isolation characteristics. 种双
