Intelligent Connected Vehicle Antenna

　　Intelligent Connected Vehicle (ICV) antennas are key components for enabling information exchange between vehicles and the outside world, supporting a variety of wireless communication technologies, such as V2X (vehicle-to-everything), 5G, Wi-Fi, Bluetooth, GNSS, etc. These antennas not only need to have high gain, wide bandwidth and good anti-interference capabilities, but also be able to adapt to complex installation environments and ensure long-term stable operation. The following are detailed information and technical features about intelligent connected vehicle antennas:

　　1. Main types and applications

　　1.1 V2X antennas

　　Function: Used for communication between vehicles and vehicles (V2V), vehicles and infrastructure (V2I), vehicles and pedestrians (V2P), and vehicles and networks (V2N).

　　Frequency band: Usually works in the 5.9 GHz DSRC (dedicated short-range communication) or C-V2X (cellular vehicle-to-everything) band.

　　Features: Supports low-latency, high-reliability communication, and can maintain a stable connection under high-speed movement.

　　1.2 5G Antenna

　　Function: Provides ultra-high-speed data transmission capabilities, supports functions such as high-definition map downloads and real-time traffic information updates required for autonomous driving.

　　Frequency band: Covers Sub-6 GHz and millimeter wave (mmWave) bands to meet the needs of different application scenarios.

　　Features: Has high bandwidth and low latency characteristics, supports large-scale MIMO (multiple input multiple output) technology, and improves data throughput.

　　1.3 Wi-Fi and Bluetooth Antenna

　　Function: Mainly used for in-car entertainment systems, smartphone connections, wireless charging and other functions.

　　Frequency band: Commonly found in 2.4 GHz and 5 GHz bands.

　　Features: Small size, easy to integrate into the internal structure of the vehicle, providing a convenient wireless connection experience.

　　1.4 GNSS Antenna

　　Function: Receive time and location information from global navigation satellite systems (such as GPS, GLONASS, Galileo, BeiDou).

　　Frequency band: L1, L2, L5 and other bands.

　　Features: High-precision positioning, support for multiple constellation systems, ensuring accurate location information is available worldwide.

　　1.5 Digital Key Antenna

　　Function: Supports keyless entry, remote start and other functions, usually using BLE (Bluetooth Low Energy) or NFC technology.

　　Features: Miniaturized design, easy to integrate into door handles, B-pillars and other locations, providing a safe and reliable user authentication mechanism.

　　2. Technical Features

　　Multi-band support: In order to adapt to different wireless technologies and application scenarios, ICV antennas usually need to support multiple bands.

　　High gain and narrow beam: Especially in V2X and 5G applications, high gain and narrow beam help improve communication quality and range.

　　Anti-interference ability: With good anti-interference performance, it reduces potential interference from other wireless devices or environmental factors.

　　IP protection level: Waterproof and dustproof, suitable for outdoor installation, especially in bad weather conditions.

　　Compact and lightweight design: Easy to integrate into the design of modern cars without destroying the overall aesthetics.

　　Adaptive beamforming: Combined with advanced signal processing algorithms, dynamically adjust the beam direction to optimize the communication effect.

　　3. Installation location

　　Roof: For example, shark fin antennas are suitable for placement in the center of the roof to provide wide coverage.

　　Rearview mirror: Integrating the antenna into the rearview mirror saves space without affecting the appearance.

　　Around the vehicle body: Multiple antennas are installed in the front and rear bumpers, side skirts, etc. to ensure all-round coverage.

　　Inside the vehicle: For short-range communications such as Wi-Fi and Bluetooth, the antenna can be hidden in internal structures such as the dashboard and seats.
