Overview

The 2042810100 is a dual-band flexible antenna designed for 2.4GHz and 5GHz wireless communications. It features a compact 35mm by 11mm PCB trace design on a PET film substrate with an adhesive backing for simple peel-and-stick integration. This antenna includes a 100mm micro-coaxial cable terminated with a standard MHF/U.FL compatible connector.

Why Choose This Part

The flexible PET film construction allows for mounting on curved surfaces inside plastic enclosures where space is at a premium. With a peak gain of 3.5dBi and a return loss better than -10dB, it offers high efficiency across both the 2.4GHz and 5GHz bands. The pre-applied adhesive and integrated 100mm cable simplify assembly by eliminating the need for complex RF layout on the main PCB.

Applications

IoT Device Connectivity
Providing reliable dual-band Wi-Fi and Bluetooth connectivity for smart home sensors and industrial gateways.
Wearable Electronics
The low-profile 0.1mm thickness makes it ideal for integration into slim wearable housings with curved surfaces.
Wireless Industrial Monitoring
Enables WirelessHART and Zigbee communication for remote monitoring equipment in factory environments.
Smart Building Automation
Suitable for Thread and BLE enabled lighting controllers and climate control units requiring internal antennas.

Getting Started

When mounting, ensure the antenna is placed away from metal components and batteries to prevent detuning. Connect the U.FL/MHF compatible connector to the RF output of your module, ensuring the cable is routed away from high-speed digital lines to minimize interference. Evaluation may require an enclosure prototype to verify the antenna performance in its final dielectric environment.
