Description

Technical Field

[0001] This utility model belongs to the field of antenna technology, and in particular relates to a vehicle-mounted integrated antenna box. Background Technology

[0002] The blueprint for 5G networks is a speed 100 times faster than 4G, reaching 10Gbit / s, with latency less than 1ms, supporting a high density of over 100 billion connections and a capacity 1000 times greater than 4G. Applying 5G antennas to vehicles to enable applications such as vehicle-to-everything (V2X) and autonomous driving will be a trend. With the development of automotive intelligence, car antennas are no longer limited to wireless LAN, mobile networks, and positioning; they also include Bluetooth antennas to enable functions such as keyless entry and IoT connectivity. The technology in domestically produced cars is becoming increasingly mature. Currently, cars are developing towards becoming intelligent terminals, rather than simply driving tools, requiring the integration of more and more antennas within the vehicle to acquire information about the vehicle, road conditions, communications, positioning, environmental perception, and information processing.

[0003] With the accelerated development of intelligent connected vehicles and smart transportation systems, vehicle-to-everything (V2X) communication technology is facing core requirements such as multi-band convergence, high integration, and low latency and high reliability. The 3GPP 5G Rel-16 to Rel-18 standards provide technical support for V2X technology. For example, Rel-16 achieves direct vehicle-to-vehicle communication (latency less than 60ms, reliability up to 99.999%) through NR Sidelink, Rel-17 extends to pedestrian interaction (V2P) and energy-saving mechanisms, and Rel-18 further optimizes multi-standard coexistence capabilities. China's "14th Five-Year Plan for the Development of the Information and Communication Industry" clearly promotes the deep integration of C-V2X with 5G and smart cities, accelerating the large-scale deployment of urban roads and highways. However, existing vehicle-mounted antenna systems need to simultaneously support multiple protocols such as 5G (downlink > 2Gbps, uplink > 200Mbps), V2X (communication distance > 300m, packet loss rate < 5%), dual-band GNSS (positioning error < 1m), and Wi-Fi 6 / BT. Traditional distributed designs suffer from problems such as large space occupation and signal interference (e.g., digital noise affecting GNSS accuracy). Therefore, this project focuses on developing an integrated multi-channel vehicle-mounted antenna system. Through electromagnetic compatibility optimization and compact structural design, it aims to solve the problem of multi-band coexistence interference and promote the evolution of vehicle-to-everything (V2X) communication towards a safer and more efficient direction.

[0004] Currently, most automotive antennas use shark fin antennas. However, with advancements in automotive technology, changes in aesthetic design, and the increasing number of communication antennas, traditional shark fin antennas can no longer accommodate all antennas and do not conform to a minimalist aesthetic. Integration into the vehicle body has become a crucial requirement for automotive antennas. Traditional GNSS navigation antennas are relatively large, and the use of double-layer stacking to cover two frequency bands results in a high profile. Summary of the Invention

It can be installed inside the vehicle without affecting the overall appearance, near the dashboard, or in other unshielded signal-free areas within the vehicle. Attached Figure Description
