Abstract
A dual-band antenna, a wireless local area network (WLAN) device, and a method for manufacturing a dual-band antenna, where the dual-band antenna includes a conductive plane, a smooth curved-surface assembly joined onto the conductive plane, and a feed pin connected to the smooth curved-surface assembly. The conductive plane is configured to function as a first antenna, for receiving and sending a radio frequency signal of a first frequency band, and the smooth curved-surface assembly is configured to function as a second antenna, for receiving and sending a radio frequency signal of a second frequency band. Hence, a curved surface of a surface of the curved-surface assembly that is used as the second antenna transits smoothly. Therefore, a current is distributed relatively evenly, and radiation efficiency is relatively high.
