[0070] The first antenna unit 1 is arranged on a first plane (not shown in the figure) and is configured to emit energy towards a direction perpendicular to the first plane to form a first radiation area A1. Thus, the first antenna unit 1 can be used to emit energy to the first radiation area A1 to realize the communication of the antenna assembly 10.

[0075] In some embodiments, the first radiators 12 can be arranged in multiple columns, and the multiple columns of the first radiators 12 can be arranged in the first plane and spaced apart in the first direction. For example, referring to FIG. 5, the first direction can be the Y-axis direction in the spatial coordinate system, and in the first plane, the first radiators 12 can be arranged in two columns in the first direction and six rows in the Z-axis direction. Alternatively, referring to FIG. 7, the first radiators 12 can be arranged in three columns. Alternatively, referring to FIG. 8, the first radiators 12 can be arranged in four columns.
