<p>Embodiments of the present invention provide a broadband dual-polarized array antenna and a base station. The broadband dual-polarized array antenna comprises an antenna unit, a metal reflection plate and a metal isolation plate, and the antenna unit is separated through the metal isolation plate, wherein the antenna unit comprises a feed plate and dual layers of radiating patches, a first end of the feed plate is arranged on a bottom-layer radiating patch in the dual layers of radiating patches to form a feed point, and a second end is connected to a feed structure to form a feed port; an upper surface of the bottom-layer radiating patch in the dual layers of radiating patches is provided with an open slot, and a hole is arranged within a scope of the open slot for fixedly connecting to the first end of the feed plate, forming capacitive reactance. According to the embodiments of the present invention, the open slot is arranged on the upper surface of the bottom-layer radiating patch of the array antenna to form the capacitive reactance, making resonance of each radiating patch in the dual layers of radiating patches of the array antenna easy to implement, and thus the array antenna be able to implement broadband, and a broadband performance be good.</p> |
