Cdsenet TXWF-PCB-4814 Dual-Band 2.4/5.8GHz Internal PCB Antenna - 2.5dBi WiFi Bluetooth Antenna with IPEX-1 Connector

?? Enhanced Dual-Band RF Performance

Simultaneously supports 2.4GHz (2400-2500MHz) and 5.8GHz (5150-5850MHz) frequency bands with improved 2.5 dBi gain, delivering 0.5dB higher performance compared to standard 2.0dBi antennas. 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, reducing BOM costs by 30-40% and simplifying mechanical design. The enhanced gain translates to approximately 12% range improvement over 2.0dBi variants in typical indoor environments.

?? Optimized 48¡Á14mm Form Factor

The 48¡Á14mm PCB radiator with 119mm RG1.13 feeder cable is engineered for applications requiring higher gain in a compact footprint. The larger radiator area (672mm2) compared to 40¡Á8mm (320mm2) and 42¡Á12mm (504mm2) variants delivers superior radiation efficiency, particularly at 5.8GHz where antenna size directly impacts performance. The rigid FR4 PCB substrate provides excellent mechanical stability under vibration and thermal cycling, maintaining consistent electrical performance in industrial environments. IPEX-1 (U.FL/MHF1) connector provides tool-free snap-on installation compatible with 95% of commercial WiFi/Bluetooth modules including ESP32, ESP8266, nRF52, Qualcomm QCA, and MediaTek MT 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. FR4 substrate resists moisture absorption (0.1% max) better than flexible materials, ensuring long-term reliability in humid environments (up to 95% RH non-condensing). The antenna maintains gain variation within ¡À0.3dB across the full temperature range.

Q: Is the TXWF-PCB-4814 compatible with ESP32 and ESP8266 WiFi modules?

A: Yes, this antenna is fully compatible with ESP32, ESP8266, and other WiFi/Bluetooth modules using standard IPEX-1 (U.FL/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 IPEX-1 connector to your module's antenna port¡ªno additional matching network required. The 2.5dBi gain provides approximately 10-15% better range compared to standard 2.0dBi antennas. Verified compatibility includes ESP32-WROOM, ESP8266-12F, nRF52840, Qualcomm QCA4020, and MediaTek MT7688 series.

Q: How do I install this internal PCB antenna inside a plastic enclosure?

A: For optimal performance, mount the 48¡Á14mm PCB radiator flat against the inside surface of your plastic enclosure, keeping it at least 10mm away from metal components and batteries. The rigid FR4 substrate provides better mechanical stability than flexible antennas, making it easier to mount using standoffs or double-sided adhesive tape. 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. The 119mm feeder cable allows flexible routing (minimum bend radius: 5mm). Position the antenna vertically or horizontally based on your device orientation for optimal omnidirectional coverage. Detailed mounting guidelines are available in the specification sheet.

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

A: The TXWF-PCB-4814 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 with gain variation within ¡À0.3dB across the full temperature range. The FR4 PCB substrate has low moisture absorption (0.1% max), providing superior long-term reliability in humid environments up to 95% RH non-condensing. 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. 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 and maximize performance.

Q: What is the expected wireless range with this 2.5 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 2.5 dBi antenna, expect 60-120 meters line-of-sight range indoors and 250-350 meters outdoors in open areas. The 2.5 dBi gain provides approximately 12% range improvement over 2.0 dBi antennas and 25% improvement over 0 dBi reference antennas. For comparison, upgrading from 2.0 dBi to 2.5 dBi adds roughly 10-15 meters of indoor range. 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). The larger 48¡Á14mm radiator provides better efficiency at 5.8GHz compared to smaller form factors.
