Product Overview
The TXWF-FPC-3710 is a compact 2.4/5.8 GHz dual-band FPC (Flexible Printed Circuit) internal antenna engineered for space-constrained WiFi and IoT wireless applications. With a measured peak gain of 2 dBi and VSWR ≤ 1.5 across both bands, it delivers reliable omnidirectional RF performance in a 37 × 10 mm footprint. The 120 mm coaxial cable with IPEX-1 (U.FL) connector enables plug-and-play integration with dual-band WiFi modules. Suitable for smart home gateways, wireless routers, IoT terminals, and industrial network devices. Updated March 2026.

Product Details
Ultra-Thin FPC Substrate — Adhesive Internal Mounting
The FPC substrate is flexible and ultra-thin, allowing direct adhesive mounting onto curved or flat non-metallic surfaces inside device enclosures. This eliminates the need for external antenna ports, maintaining a clean product exterior while preserving 2 dBi gain across both 2.4 GHz and 5.8 GHz bands. Keep at least 5 mm clearance from metal components to avoid detuning.
IPEX-1 (U.FL) Connector — Plug-and-Play Module Integration
The 120 mm coaxial cable terminates in a standard IPEX-1 (U.FL) connector, compatible with the majority of dual-band WiFi modules including Qualcomm, MediaTek, and Realtek chipset-based designs. The snap-lock mechanism ensures a secure, low-loss connection with insertion loss typically below 0.3 dB at 5.8 GHz.
Professional Test Report
VSWR measured at ≤ 1.5 across 2.4–2.5 GHz and 5.15–5.8 GHz using an Agilent E5071C Vector Network Analyzer. Return loss > 14 dB on both bands confirms efficient power transfer with minimal reflection.
Ideal Applications

Q: Which WiFi modules and chipsets is the TXWF-FPC-3710 compatible with?
A: The TXWF-FPC-3710 is compatible with any dual-band WiFi module featuring a 50 Ω IPEX-1 (U.FL) port, including modules based on Qualcomm QCA, MediaTek MT7612/MT7622, Realtek RTL8812, and Espressif ESP32 chipsets. It supports IEEE 802.11a/b/g/n/ac standards across 2.4–2.5 GHz and 5.15–5.8 GHz. Verify that your module's U.FL port matches the IPEX-1 connector generation before installation.
Q: How should I install this antenna inside a device enclosure?
A: Clean the mounting surface with isopropyl alcohol and allow it to dry. Peel the adhesive backing and press the FPC antenna firmly onto a flat or gently curved non-metallic (plastic or PCB) surface. Maintain at least 5 mm clearance from metal components or ground planes to prevent detuning. Route the 120 mm cable without sharp bends (minimum bend radius: 5 mm) and snap the IPEX-1 connector onto the module's U.FL port until it clicks. Never mount directly behind metal shielding cans.
Q: What are the environmental and temperature ratings?
A: The TXWF-FPC-3710 FPC substrate operates reliably across -40°C to +85°C, suitable for industrial and automotive applications when housed in an appropriately rated enclosure. The product is RoHS compliant, free from lead, mercury, cadmium, and other restricted hazardous substances. It is an internal antenna and requires a sealed enclosure for outdoor or high-humidity deployments.
Q: Can this antenna be used inside a metal enclosure?
A: No. Metal enclosures cause significant signal attenuation and will detune the antenna, degrading VSWR well above 1.5 and reducing effective gain. The TXWF-FPC-3710 must be mounted inside non-metallic (plastic, fiberglass, or ABS) housings. If a metal enclosure is required, use an external antenna with a bulkhead SMA connector instead.
Q: Does this antenna support simultaneous 2.4 GHz and 5.8 GHz operation?
A: Yes. The TXWF-FPC-3710 is a true dual-band antenna with a single feed point, maintaining VSWR ≤ 1.5 and 2 dBi gain across both 2.4–2.5 GHz and 5.15–5.8 GHz simultaneously. This makes it suitable for dual-band concurrent WiFi routers and access points without requiring separate antennas for each band.
