In the era of smart mobility, V2X (Vehicle-to-Everything) communication and precise navigation have become core requirements for intelligent vehicles. A global leading automotive parts supplier faced critical challenges when developing integrated smart car solutions, prompting them to partner with Tengxiang Electronics—an experienced OEM/ODM antenna manufacturer with 12 years of industry expertise.

Client Background

The client specializes in supplying key electronic components to mainstream automakers, focusing on integrating V2X communication and navigation functions into mid-to-high-end smart vehicle models. With a monthly demand for 50,000+ antenna units, they needed a reliable partner capable of custom development, stable bulk supply, and compliance with automotive industry quality standards.

Core Pain Points

1. Space Constraints: The need to integrate WiFi (for data transmission) and GNSS (for positioning) functions into a single component to save limited installation space in the vehicle.

2. Signal Instability: Frequent signal dropout and lag during high-speed driving (exceeding 150km/h) and in complex road conditions such as tunnels and mountainous areas.

3. Electromagnetic Interference: Poor electromagnetic compatibility (EMC) with other vehicle electronic systems, leading to distorted communication signals.

4. Strict Quality Requirements: Compliance with IATF16949 automotive quality certification and military-grade vibration resistance to withstand long-term vehicle operation.

Tengxiangs Custom Solution

Leveraging our core strengths in antenna R&D and manufacturing, Tengxiangs team delivered a targeted solution:

1. Integrated Design: Developed a compact WiFi+GNSS combined antenna with a low-profile structure (thickness <10mm), supporting both WiFi 6e data transmission and multi-satellite (GPS/BeiDou/GLONASS) GNSS positioning. Flexible installation options (embedded or roof-mounted) adapted to different vehicle models.

2. Anti-Interference & Durability: Adopted advanced electromagnetic shielding technology to isolate interference from vehicle engines and electronic devices. Conducted military-grade vibration tests and EMC testing to meet automotive industry standards.

3. Bulk Supply Capability: Backed by a 10,000㎡ production base, 8 production lines, and a monthly capacity of 500K PCS, ensuring on-time delivery for bulk orders with a 3-week lead time.

Implementation & Testing

Tengxiangs R&D team collaborated closely with the clients engineering department, completing the initial prototype design in just 2 weeks. The antenna underwent over 20 rigorous tests, including VSWR (Voltage Standing Wave Ratio) testing, 1000-hour vibration testing, thermal shock testing (-40℃ to 85℃), and EMC compatibility testing—all conducted in our in-house laboratories equipped with professional testing equipment.

After three rounds of prototype optimization, the final product passed IATF16949 certification and the clients on-vehicle validation, confirming its reliability in real-world conditions.

Project Outcomes

Stable Performance: The combined antenna maintained stable signal transmission at speeds up to 180km/h, with zero V2X data lag or navigation drift in complex road environments.

Long-Term Cooperation: The client placed continuous repeat orders, with the antenna integrated into 2 mainstream smart vehicle models.

Quality Recognition: The products defect-free rate exceeded industry standards by 30%, aligning with Tengxiangs commitment to military-grade quality control.
