This 2.4 GHz wire-fed RF antenna features a composite radiating structure consisting of a copper tube, copper posts, and springs. With an exposed wire length of 150 mm, it can be flexibly installed to accommodate the internal space of the device. Designed with a characteristic impedance of 50 Ω, the antenna operates within a frequency range of 2.4 GHz to 2.5 GHz, with a standing wave ratio (SWR) of ≤2.0 and a typical peak gain of 3 dBi, offering excellent impedance matching and stable signal transmission.

With its compact structure and high radiation efficiency, this antenna is suitable for internal installation in wireless devices with limited space. The combination of copper tubing, copper posts, and springs effectively enhances the antenna’s performance and reliability. It can be widely applied to Wi-Fi devices, wireless communication modules, IoT terminals, smart home devices, industrial control equipment, smart gateways, wireless data transmission devices, and other products operating in the 2.4 GHz band, providing stable and reliable wireless connectivity for these devices.
