Cdsenet TXWF-PCB-4008 Dual-Band 2.4/5.8GHz Built-in PCB Antenna - 2.0dBi WiFi Bluetooth FPC Antenna with IPX Connector

?? Dual-Band RF Performance

Simultaneously supports 2.4GHz (2400-2500MHz) and 5.8GHz (5150-5850MHz) frequency bands with consistent 2.0 dBi gain, enabling reliable WiFi 802.11b/g/n/ac and Bluetooth 4.0/5.0 connectivity. Laboratory measurements using Agilent E5071C network analyzer confirm VSWR ¡Ü1.5 across the entire operating range, ensuring >90% power transfer efficiency and minimal signal reflection. This dual-band capability eliminates the need for separate antennas in multi-protocol IoT devices.

?? Ultra-Compact Integration Design

The 40¡Á8mm PCB radiator with 120mm RG1.13 feeder cable is engineered for space-constrained applications where traditional external antennas are impractical. The flexible FPC substrate allows mounting inside plastic enclosures with minimal performance degradation (typical 0.5-1.0 dB loss through ABS/PC housings). IPX (MHF1) connector provides tool-free snap-on installation compatible with 95% of commercial WiFi/Bluetooth modules including ESP32, ESP8266, nRF52, and Qualcomm QCA series chipsets.

??? Industrial-Grade Reliability

Validated for -40¡ãC to +85¡ãC operation with <500 hours MTBF testing per MIL-STD-810G thermal cycling protocols. RoHS-compliant materials and FCC/CE certification ensure regulatory compliance for commercial deployment in North America, EU, and Asia-Pacific markets. The 50¦¸ impedance matching network maintains stable performance across temperature extremes, making it suitable for outdoor IoT sensors, automotive telematics, and industrial automation equipment.

Q: Is the TXWF-PCB-4008 compatible with ESP32 and ESP8266 WiFi modules?

A: Yes, this antenna is fully compatible with ESP32, ESP8266, and other WiFi/Bluetooth modules using standard IPX (IPEX-1/MHF1) connectors. The 50¦¸ impedance matches the RF output of these modules, and the dual-band design supports both 2.4GHz (802.11b/g/n) and 5.8GHz (802.11ac) protocols. Simply connect the IPX connector to your module's antenna port¡ªno additional matching network required. Verified compatibility includes ESP32-WROOM, ESP8266-12F, nRF52840, Qualcomm QCA4020, and MediaTek MT7688 series.

Q: How do I install this built-in PCB antenna inside a plastic enclosure?

A: For optimal performance, mount the 40¡Á8mm PCB radiator flat against the inside surface of your plastic enclosure, keeping it at least 10mm away from metal components and batteries. The flexible FPC substrate allows bending the feeder cable as needed (minimum bend radius: 5mm). Use double-sided adhesive tape or the mounting holes (if present) to secure the antenna. For ABS/PC enclosures ¡Ü3mm thick, expect <1dB signal loss. Avoid placing the antenna near LCD displays, motors, or switching power supplies which can cause RF interference. Detailed mounting guidelines are included in the downloadable datasheet.

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

A: The TXWF-PCB-4008 is rated for -40¡ãC to +85¡ãC continuous operation, making it suitable for outdoor and automotive applications. The antenna has passed 500-hour thermal cycling tests per MIL-STD-810G standards and maintains VSWR ¡Ü1.5 across the full temperature range. While the antenna itself is not waterproof (no IP rating), it can be used in weatherproof enclosures for outdoor IoT deployments. The RoHS-compliant materials resist UV degradation and humidity. For marine or high-salt environments, consider conformal coating the PCB radiator for additional corrosion protection.

Q: Can I use this antenna for both WiFi and Bluetooth simultaneously?

A: Yes, the dual-band design supports concurrent WiFi and Bluetooth operation on modules with combo chipsets (e.g., ESP32, Cypress CYW43455). The 2400-2500MHz coverage includes both WiFi channels 1-14 and Bluetooth/BLE 2.4GHz band. However, note that WiFi and Bluetooth share the same 2.4GHz spectrum, so your module's firmware must implement proper coexistence mechanisms to avoid interference. For applications requiring simultaneous high-throughput WiFi and Bluetooth, consider using WiFi on the 5.8GHz band (if your module supports 802.11ac) to eliminate spectrum contention.

Q: What is the expected wireless range with this 2.0 dBi antenna?

A: Wireless range depends on multiple factors including transmit power, receiver sensitivity, and environmental conditions. With a typical WiFi module (20 dBm TX power) and this 2.0 dBi antenna, expect 50-100 meters line-of-sight range indoors and 200-300 meters outdoors in open areas. The 2.0 dBi gain provides a good balance between omnidirectional coverage and compact size. For comparison, a 0 dBi antenna would reduce range by ~20%, while a 5 dBi antenna would increase range by ~40% but with a narrower radiation pattern. Actual performance will vary based on obstacles (walls, furniture), interference from other 2.4/5.8GHz devices, and module sensitivity (-90 to -95 dBm typical for WiFi).
