8-2118908-1 is a Wi-Fi 6/6E triple-band on-board antenna designed for high-performance wireless connectivity applications. The antenna operates across three frequency bands: 2400–2485 MHz (2.4 GHz), 5150–5875 MHz (5 GHz), and 5925–7125 MHz (6 GHz), providing global frequency coverage and supporting Wi-Fi 6, Wi-Fi 6E, Bluetooth, and ZigBee protocols. It features an SMD-mounted PCB integrated antenna (IFA) with a compact size of 18.9 mm × 6.2 mm × 0.76 mm, linear polarization, 50-ohm feed point impedance, and power handling capability of 10 watts CW. The antenna delivers peak gains of 2.3 dBi (2.4 GHz and 6 GHz bands) and 2.8 dBi (5 GHz band), with average efficiencies of 80–85% across the operating bands and VSWR performance below 2.5:1. This antenna is ideal for IoT devices, wireless routers, access points, and embedded systems requiring multi-band connectivity with minimal PCB keep-out zone requirements and reliable performance across industrial temperature ranges of -40°C to +85°C.
