Overview

The 2042811100 is a dual-band Wi-Fi PCB trace antenna designed for high-performance wireless connectivity across 2.4GHz and 5GHz bands. It features a flexible PCB material with adhesive mounting and a 100mm micro-coaxial cable terminated with an I-PEX MHF4L connector. This ultra-thin component is optimized for integration into compact device housings where internal space is limited.

Why Choose This Part

This antenna offers excellent signal integrity with a return loss of -10dB and supports the latest Wi-Fi standards including Wi-Fi 6E. Its flexible PCB construction and peel-and-stick adhesive backing simplify mechanical integration into non-standard geometries. The use of the MHF4L connector ensures compatibility with modern, low-profile wireless modules and M.2 cards.

Applications

IoT Gateways
