　　Anti-interference and Environmental Adaptability

　　Interference Shielding: For the 2.4GHz band (susceptible to interference from microwave ovens and Bluetooth devices), it adopts "adaptive filtering + dynamic impedance adjustment" technology, achieving an interference suppression ratio ≥40dB and reducing the transmission error rate to ≤0.001%.

　　Extreme Environment Adaptability:

　　Industrial Grade Model: Temperature resistant -40℃~85℃, salt spray resistant (500 hours, 5% NaCl concentration), vibration resistant (10-2000Hz, 15G acceleration), suitable for factories, mines, and other scenarios;

　　Outdoor Model: IP67 waterproof and dustproof (immersion in 1 meter of water for 30 minutes without failure), UV resistant (1000 hours of exposure). Performance degradation ≤5% per hour, suitable for base stations, campsites, and other scenarios.

　　Miniaturization and Integration Adaptation

　　Small Device Compatibility: The built-in antenna uses a "multi-layer PCB stack-up + LDS laser engraving" process, reducing its size by 30% compared to traditional antennas. It can be embedded in devices with a thickness ≤5mm (such as smartwatches and miniature IoT sensors) without affecting the device's appearance or feel.

　　Multi-Hardware Collaboration: When used with VLG WiFi modules and ultra-fine FPC harnesses (0.08mm²), signal transmission loss is ≤3dB (10-meter distance). It supports integrated debugging of "antenna-module-harness," shortening the integration cycle to 1-2 weeks.
