AI Technical Summary
Traditional vehicle array antennas use a static layout, which occupies external space of the vehicle and affects communication quality and the overall appearance of the vehicle.
Antennas in both conventional and millimeter-wave bands are integrated into the wiper arms and blades. Dynamic antenna pointing is achieved through dynamic scanning of the wiper, improving environmental awareness and communication quality.
It significantly improves the vehicle's environmental perception and communication quality, while optimizing space utilization and exterior design, avoiding additional space occupation in the vehicle.
