This dual-band, direct-connect external RF antenna assembly features a black G20 design, an internal PCB antenna structure, and SMA male-to-female connectors for quick connection and stable installation. The antenna supports dual-band operation at 2.4 GHz–2.5 GHz and 5.15 GHz–5.85 GHz, with a characteristic impedance of 50 Ω. In the 2.4 GHz band, the standing wave ratio (SWR) is ≤2.0 and the peak gain is 3 dBi; in the 5.8 GHz band, the SWR is ≤2.0 and the peak gain is 5 dBi, providing excellent signal coverage and transmission performance.

This antenna features dual-band compatibility, a compact design, and stable performance. It is suitable for a wide range of wireless communication devices and can be widely applied to Wi-Fi devices, wireless modules, smart home devices, IoT terminals, industrial control equipment, wireless gateways, smart terminals, and other 2.4 GHz/5.8 GHz dual-band communication products, providing efficient and reliable wireless signal connectivity for these devices.
