Internal PCB Antenna 2400-2500MHz / 5150-5850MHz Dual-Band Wi-Fi (P/N 10035924 / 20S1539A, IPEX U.FL Connector)

Optimize embedded wireless performance in your compact IoT devices, routers, and robotics platforms with the 10035924 (20S1539A) high-efficiency internal PCB antenna. Designed for multi-band wireless communications, this omnidirectional printed circuit board antenna covers both 2.4 GHz and 5 GHz frequency bands, delivering reliable gain for Wi-Fi 4/5/6 (802.11a/b/g/n/ac/ax), Bluetooth, and Zigbee connectivity.

Equipped with a micro coax cable terminating in an industry-standard IPEX U.FL (MHF1) connector and backed with 3M self-adhesive tape, this internal antenna offers easy peel-and-stick installation inside plastic or fiberglass enclosures. Its low profile makes it an ideal replacement or upgrade for embedded systems, smart home hubs, FPV ground station receivers, mini PCs, and custom IoT hardware where clean, internal antenna placement is required.

Key Features:

• Dual-Band Spectrum Support: Covers both 2.4 GHz (2400–2500 MHz) and 5 GHz (5150–5850 MHz) bands for multi-protocol compatibility.

• Compact PCB Design: Space-saving form factor engineered for seamless integration inside plastic and non-metallic device housings.

• IPEX / U.FL Connector: Standard MHF1/U.FL coaxial interface connects directly to standard Wi-Fi/Bluetooth modules (ESP32, Raspberry Pi Compute Module, Mini PCIe / M.2 cards).

• 3M Adhesive Backing: Strong peel-and-stick mounting allows rapid and secure placement on internal enclosure walls.

• High Radiation Efficiency: Provides consistent omnidirectional coverage without external external whip antennas.
