1. An antenna assembly, comprising:
a dielectric substrate, wherein a first surface of the dielectric substrate comprises a ground plane and a closed clearance region located in the ground plane;
an antenna unit comprising a first antenna unit and a second antenna unit, the first antenna unit and the second antenna unit being spaced apart on the first surface of the dielectric substrate and located in the closed clearance region, and the first antenna unit and the second antenna unit being orthogonally arranged;
a radio frequency chip, arranged on the dielectric substrate and connected with the first antenna unit and the second antenna unit respectively; and
a metal resonant cavity, arranged on a second surface of the dielectric substrate, wherein in a direction perpendicular to the second surface, at least a part of a projection of the closed clearance region on the metal resonant cavity is within an outer contour of the metal resonant cavity.
