Cdsenet TXWF-PCB-3810 Dual-Band WiFi Antenna 2.4/5.8GHz 2.0dBi - IoT PCB Antenna IPX

Dual-Band Frequency Coverage

Simultaneous support for 2.4 GHz (2400-2500 MHz) and 5.8 GHz (5150-5850 MHz) bands enables compatibility with WiFi 4/5/6 standards (802.11n/ac/ax), Bluetooth 4.x/5.x, and Zigbee protocols. The dual-band architecture reduces interference in congested 2.4GHz environments while providing high-throughput 5GHz connectivity. Measured radiation efficiency exceeds 75% across both operating bands.

Compact FPC Built-in Design

The ultra-thin 38mm ¡Á 10mm flexible printed circuit design allows integration into space-constrained enclosures with internal volumes as small as 50cm3. The FPC substrate provides mechanical flexibility for mounting on curved surfaces or tight internal cavities in IoT modules, routers, and embedded systems. Weight: 0.8g (excluding cable).

IPX Connector Standard Interface

Equipped with industry-standard IPX 1st generation (IPEX-1/U.FL) micro-coaxial connector, ensuring compatibility with ESP32, Raspberry Pi, Arduino WiFi shields, and commercial wireless modules from Espressif, Qualcomm, and MediaTek. The 50¦¸ impedance matching minimizes insertion loss (0.3dB typical) and maintains signal integrity across the 120mm feeder cable.

?? Laboratory-Verified Performance Testing

VSWR measurements conducted using Agilent E5071C ENA Series Network Analyzer (calibrated to NIST standards). Test results demonstrate VSWR ¡Ü1.5 across 2400-2500 MHz and 5150-5850 MHz bands, indicating >96% power transfer efficiency. Return loss measured at -14dB @ 2.45GHz and -16dB @ 5.8GHz, meeting 3GPP TS 34.114 and IEEE 802.11 antenna performance requirements.

Q: Is this antenna compatible with ESP32, Raspberry Pi, and Arduino WiFi modules?

A: Yes, the IPX 1st generation connector (also known as IPEX-1 or U.FL) is the standard interface for ESP32-WROOM-32, ESP32-S3, Raspberry Pi Compute Module 4, and most commercial WiFi/Bluetooth modules including those from Espressif, Qualcomm Atheros, and MediaTek. The 50¦¸ impedance matches standard WiFi chipsets. Verify your module uses IPEX-1 connector (not IPEX-4 MHF4 which requires an adapter). Compatible with modules operating at 2.4GHz (802.11b/g/n) and 5GHz (802.11a/n/ac) frequencies.

Q: How do I install this FPC antenna inside a device enclosure?

A: The flexible PCB design allows mounting using adhesive backing (3M VHB tape recommended) or mechanical clips. Position the 38mm ¡Á 10mm radiator element at least 10mm away from metal surfaces to prevent detuning. For plastic enclosures (ABS, PC, PMMA), mount the antenna flat against the interior wall. Route the 120mm feeder cable away from high-current traces, switching power supplies, and LCD displays to minimize EMI. The IPX connector requires 2-3N insertion force and should click audibly when properly seated. Avoid sharp bends in the feeder cable (minimum bend radius: 5mm).

Q: What is the operating temperature range and environmental durability?

A: The TXWF-PCB-3810 operates reliably across -40¡ãC to +85¡ãC ambient temperature range, suitable for industrial and automotive applications. The FPC substrate maintains stable electrical characteristics across this range with <0.2dB gain variation. While the antenna itself has no IP rating (designed for internal mounting), the materials are RoHS compliant and resistant to humidity up to 95% RH non-condensing. For outdoor applications, mount inside a weatherproof enclosure with RF-transparent window (polycarbonate or ABS recommended).

Q: What wireless range can I expect with this 2.0dBi antenna?

A: Range depends on transmit power, receiver sensitivity, and environment. With typical 20dBm (100mW) WiFi modules at 2.4GHz, expect 50-100m indoor range (through 2-3 walls) and 200-300m line-of-sight outdoor. At 5.8GHz, range reduces by approximately 30% due to higher path loss. The 2.0dBi gain provides balanced omnidirectional coverage (¡À30¡ã elevation beamwidth) suitable for gateway and sensor applications. For extended range, consider pairing with a higher-gain external antenna (5-9dBi) or increasing transmit power within regulatory limits (FCC: 30dBm EIRP max for 2.4GHz).

Q: Does this antenna require FCC or CE certification for my product?

A: The antenna itself does not require separate certification, but your complete wireless device must undergo FCC Part 15 (USA), CE RED (Europe), or equivalent regional testing. This antenna's measured performance data (gain, VSWR, radiation pattern) can be submitted as part of your device's certification documentation per 3GPP TS 34.114 and ETSI EN 300 328 standards. The antenna is designed to support compliance testing with VSWR ¡Ü1.5 ensuring minimal harmonic radiation. For intentional radiators, you may use FCC modular approval if your WiFi module is pre-certified and the antenna gain does not exceed the module's certified gain by >3dBi.
