Product Details
30 × 14mm Ultra-Compact FPC — Smallest-Class 2.4GHz Internal Antenna
At just 30 × 14mm, the TX2400-FPC-3014 is designed for devices where PCB space is the primary constraint — including smart home sensors, wireless smart locks, compact IoT gateways, and wearable devices. The FPC substrate conforms to curved inner surfaces with a 3M adhesive backing, enabling tool-free mounting without modifying the enclosure. Despite its compact size, the antenna achieves 2.5 dBi gain with VSWR 1.18 at 2.5GHz, meeting the performance requirements of WiFi 802.11b/g/n, Bluetooth 5.x, ZigBee 3.0, and Thread protocols.
Gold-Plated IPEX-I Connector with 118mm Feeder
The gold-plated IPEX-I (U.FL-compatible) connector mates directly with ESP32, ESP8266, nRF52840, CC2652, and other 2.4GHz wireless SoCs and modules with IPX-I antenna ports. The 118mm coaxial feeder provides routing flexibility inside compact IoT enclosures while maintaining signal integrity across the full 2.4–2.5GHz band. Cable length is customizable per order for high-volume production runs. Press-fit installation requires no soldering.
Professional Test Report
Measured with a vector network analyzer (Agilent E5071C equivalent): VSWR = 1.18 @ 2.5 GHz, confirming ≤1.5 across the full 2.4–2.5 GHz operating band. Return loss ≈ 21 dB at the measured frequency point.

Q: Which 2.4GHz protocols does the TX2400-FPC-3014 support?
A: The 2.4–2.5GHz frequency range covers all major 2.4GHz ISM band protocols: WiFi 802.11b/g/n (2.412–2.484GHz), Bluetooth Classic and BLE 5.x (2.402–2.480GHz), ZigBee 3.0 (2.405–2.480GHz), Thread, Matter, and proprietary 2.4GHz FSK/GFSK protocols. It is compatible with any 2.4GHz wireless module or SoC with an IPEX-I (U.FL) antenna port, including ESP32, ESP8266, nRF52840, CC2652, and Si4463-based designs.
Q: Can this antenna be installed inside a metal enclosure?
A: No. Placing any FPC antenna inside a metallic housing causes severe signal attenuation due to RF shielding. The TX2400-FPC-3014 must be mounted on the inner surface of a non-metallic (ABS, PC, or TPEE) enclosure with a minimum 3mm clearance from metal components. At 2.4GHz, even partial metal coverage can significantly degrade antenna performance. For metal enclosures, use an external 2.4GHz antenna with a bulkhead SMA connector routed through a feedthrough.
Q: How do I mount the TX2400-FPC-3014 inside my device?
A: Peel the 3M adhesive backing and press the FPC flat against the inner wall of a non-metallic enclosure, oriented parallel to the enclosure wall. Route the 118mm coaxial feeder to your 2.4GHz module's IPEX-I socket and press-fit the connector until it clicks. Keep the antenna at least 3mm from the PCB ground plane, battery, and metal shielding cans. Avoid routing the feeder cable parallel to other RF traces. No soldering is required.
Q: Can the 118mm cable length be customized?
A: Yes. The standard cable length is 118mm, but custom lengths are available per order for high-volume production runs. Contact CDSENET with your required cable length when placing a bulk order. Note that longer cables introduce additional insertion loss at 2.4GHz — each additional 100mm of standard coaxial cable adds approximately 0.3–0.5 dB of loss, which should be accounted for in the system link budget.
Q: What is the operating temperature range and is it suitable for outdoor IoT deployments?
A: The TX2400-FPC-3014 is rated for -40°C to +85°C. The FPC substrate is RoHS-compliant and resistant to humidity under standard operating conditions. For outdoor deployments, ensure the host enclosure provides IP65 or higher sealing. The antenna itself is not independently IP-rated and must be protected by the device enclosure from direct rain, UV exposure, and condensation.
