An antenna unit, an antenna module, an antenna system and a communication device, which relate to the technical field of communications. The antenna unit comprises a bottom plate, a first side plate and a second side plate. The first side plate and the second side plate are respectively connected to two sides of the bottom plate in a first direction, and the first side plate and the second side plate are spaced apart, such that the structure of the antenna unit can achieve horizontal polarization; and the antenna unit is of a symmetrical structure, and a feed point is located on the plane of symmetry of the antenna unit, such that by using the plane of symmetry as a dividing plane, the antenna unit can be equivalently divided into a first antenna portion and a second antenna portion, and the first antenna portion and the second antenna portion are connected in parallel to form a two-element array, thereby facilitating the antenna unit having a higher radiation intensity and realizing the miniaturization of the antenna unit.
