This 2.4GHz + 5.8GHz dual-band FPC (Flexible Printed Circuit) internal antenna is a compact, high-performance RF solution designed for built-in WiFi, Bluetooth, and IoT wireless applications. It features a flexible FPC structure with an adhesive sticker mount, available with either an IPEX/U.FL connector or a direct solderable pin for easy integration into space-constrained devices. Optimized for 2.4GHz (WiFi/Bluetooth/Zigbee) and 5.8GHz (WiFi) bands, this low-profile antenna delivers stable signal transmission, excellent anti-interference performance, and reliable connectivity for smart home, industrial, and consumer electronics.
Key Features
✅
Dual Band CompatibilityFully optimized for the
2.4GHz (2400-2500MHz) and
5.8GHz (5150-5850MHz) ISM bands, supporting WiFi 802.11b/g/n/ac/ax, Bluetooth, Zigbee, and other 2.4/5.8GHz wireless protocols. Ideal for dual-band routers, IoT gateways, and smart devices.
✅
Flexible FPC Sticker DesignConstructed with thin, flexible FPC material and equipped with a strong 3M adhesive backing, the antenna can be easily mounted on flat or curved surfaces inside devices. The low-profile form factor fits perfectly in compact enclosures like laptops, wearables, and small IoT sensors.
✅
Dual Connector OptionsAvailable with two termination types to match different integration needs:
IPEX/U.FL Connector: For quick, tool-free connection to WiFi/Bluetooth modules (ideal for modular devices)
Solderable Pin: For direct PCB soldering (ideal for permanent, high-reliability installations)
✅
High Gain & Low LossDesigned with optimized trace patterns for consistent gain (typically 1.5-2dBi) across both bands, minimizing signal attenuation and ensuring reliable wireless performance even in metal-enclosed or shielded environments.
✅
50Ω Impedance MatchingStandard 50Ω impedance design ensures optimal RF performance, minimizing signal reflection (VSWR ≤ 1.5) and maximizing power transfer for stable, high-speed wireless links.
✅
Industrial-Grade DurabilityHigh-quality FPC material and gold-plated contacts resist oxidation, corrosion, and mechanical stress. The antenna operates reliably across a wide temperature range (-40°C to +85°C), suitable for both indoor and industrial use.
