In the era of smart automobiles, automotive antennas, serving as the "nerve endings" for vehicle-to-externalcommunication, are undergoing a transformation from single-function components to intelligent hubs.

         They are not merely receivers of radio signals but also enable navigation, vehicle-to-everything (V2X) communication, 

emergency rescue, and other critical functions.
