Overview

The 2118309-1 is a dual-band PCB trace antenna designed for high-performance wireless connectivity across the 2.4GHz and 5GHz frequency spectrums. It features a compact adhesive-mount form factor and includes a 120mm coaxial cable terminated with a U.FL (MHF1) connector for easy integration into internal device enclosures.

Why Choose This Part

This antenna offers a high peak gain of 3.7dBi and a low VSWR of 2.0, ensuring efficient power transfer and extended range. The flexible PCB design and adhesive backing simplify mechanical integration into slim enclosures where space is limited.

Applications

WLAN and Wi-Fi 6 Networking
Provides reliable dual-band coverage for IEEE 802.11 a/b/g/n/ac/ad applications in residential and industrial gateways.
IoT Sensor Nodes
Ideal for Zigbee and Bluetooth Low Energy (BLE) devices requiring an internal antenna with higher gain than a standard chip antenna.
Smart Home Appliances
The adhesive mounting allows for flexible placement inside plastic housings of smart appliances to optimize signal propagation.

Getting Started

To integrate this antenna, ensure the mounting surface is clean and free of metal interference within the keep-out zone specified in the datasheet. Connect the U.FL termination to the RF output of your wireless module, such as an ESP32 or NXP RW612, ensuring the 120mm cable is routed away from high-speed digital lines.
