Product Overview
The TX2400-FPC3-5015 is a compact built-in FPC (Flexible Printed Circuit) antenna designed for the 2.4–2.5 GHz ISM band, covering WiFi 802.11b/g/n, Bluetooth 5.x, Zigbee, and Thread protocols. Measuring 50 × 15 mm with a 2.5 dBi peak gain and a measured VSWR of 1.18 @ 2.45 GHz, it delivers verified impedance matching with minimal power loss. The IPEX-3 (MHF3) connector with a 120 mm RG0.81 coaxial feeder ensures compatibility with modern low-profile wireless modules. Suited for smart home gateways, WiFi routers, industrial IoT modules, and consumer electronics. Updated March 2026.

Product Details
High-Toughness FPC Substrate — Adhesive-Backed Flexible Installation
The FPC substrate (thickness < 0.3 mm) features a pressure-sensitive adhesive backing for direct attachment to the inner walls of plastic enclosures. It tolerates repeated bending with a minimum radius of 5 mm and conforms to curved surfaces, enabling seamless integration into slim routers, smart speakers, and IoT sensor housings where rigid PCB antennas cannot be accommodated.
IPEX-3 (MHF3) Connector — Ultra-Compact Low-Profile Mating
The IPEX Generation 3 (MHF3) connector has a mated height of just 1.0 mm — 30% lower than IPEX-1 (U.FL) — making it the preferred interface for ultra-thin modules such as Intel AX200/AX210, Qualcomm QCA6174, and MediaTek MT7921 Wi-Fi chipsets. The 120 mm RG0.81 coaxial feeder introduces < 0.4 dB insertion loss at 2.45 GHz, preserving the full 2.5 dBi gain budget.
Professional Test Report
Measured with a vector network analyzer: VSWR = 1.18 @ 2.45 GHz, confirming excellent 50 Ω impedance matching and < 0.1 dB return loss contribution across the 2.4–2.5 GHz band.

Q: Is the TX2400-FPC3-5015 compatible with standard IPEX-1 (U.FL) connectors?
A: No. This model uses an IPEX-3 (MHF3) connector, which is physically smaller than IPEX-1 (U.FL) and not cross-compatible. IPEX-3 is commonly found on Intel AX200/AX210, Qualcomm QCA6174, and MediaTek MT7921 Wi-Fi modules. Before ordering, verify that your wireless module’s antenna port is labeled MHF3 or IPEX Gen-3. An adapter cable (MHF3 to U.FL) is available if needed.
Q: Which WiFi and Bluetooth chipsets is this antenna compatible with?
A: The TX2400-FPC3-5015 is compatible with any 2.4 GHz wireless module featuring a 50 Ω IPEX-3 (MHF3) antenna port, including Intel AX200/AX210 (Wi-Fi 6/6E 2.4 GHz chain), Qualcomm QCA9377/QCA6174, MediaTek MT7921/MT7612, and Espressif ESP32 variants with external antenna options. The measured VSWR of 1.18 @ 2.45 GHz ensures no additional matching network is required.
Q: How should the antenna be positioned for optimal 2.4 GHz performance?
A: Adhere the FPC element to the inner surface of a non-metallic (ABS, PC, or nylon) enclosure wall, maintaining at least 5 mm clearance from PCB ground planes, metal shields, and battery cells. Orient the antenna vertically for maximum omnidirectional coverage. Avoid routing the 120 mm feeder cable parallel to the FPC element, as coupling can increase VSWR and reduce effective gain.
Q: What is the operating temperature range and environmental suitability?
A: The TX2400-FPC3-5015 is rated for −40 °C to +85 °C, suitable for indoor consumer electronics, smart home devices, and light industrial environments. The FPC substrate is RoHS-compliant. For high-humidity deployments, apply conformal coating over the FPC radiating element or house it inside a sealed IP-rated enclosure to prevent moisture-induced detuning.
Q: Can the 120 mm feeder cable length be customized for OEM production?
A: Yes. The standard feeder is 120 mm RG0.81 coaxial cable, introducing < 0.4 dB insertion loss at 2.45 GHz. Custom lengths are available for OEM orders — shorter cables reduce loss further, while cables up to ~200 mm add approximately 0.3–0.6 dB additional loss at 2.4 GHz.
