摘要： This application discloses a dual-polarized antenna, a radio frequency front-end apparatus, and a communications device. The dual-polarized antenna is a planar antenna, and a maximum radiation direction of the dual-polarized antenna is parallel to an antenna plane. In this way, a radio frequency circuit may be disposed in a reverse direction of the maximum radiation direction of the dual-polarized antenna and located on a same circuit board as the dual-polarized antenna, a low profile feature is implemented, and the radio frequency circuit and the dual-polarized antenna do not need to be connected by using an interconnection plug, thereby reducing an insertion loss and reducing an assembly difficulty.
