Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of International Application No. PCT/CN2023/139967, filed on December 19, 2023, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD The present application relates to the technical field of antennas, in particular to an antenna assembly and a vehicle. BACKGROUND Vehicles rely on a positioning antenna to achieve functions such as satellite positioning and vehicle navigation. In traditional solutions, the positioning antenna is typically disposed inside an antenna box or a shark fin. However, placing the antenna box inside the vehicle subjects the positioning antenna to shielding from the autobody metal and to electromagnetic interference from electrical circuit, thereby weakening the signal reception performance of the positioning antenna. Moreover, the placement of the shark fins can interfere with the design of the panoramic sunroofs, and they are being used less and less in modern vehicle designs. Therefore, the positioning antenna provided by traditional solutions can no longer fully meet the evolving needs of vehicle development.
