Abstract: Implementations in the application provide wearable devices. In an implementation, a wearable device includes a housing, a printed circuit board (PCB), a feeding unit, and a switch. The housing includes a metal portion configured as an antenna radiator. The PCB is disposed in the housing and disposed opposite to the metal portion. The feeding unit is electrically connected to a first end of the metal portion and feeds the antenna radiator. One end of the switch is electrically connected to a second end of the metal portion, and the other end of the switch is grounded. The switch has a first switch state or a second switch state, and an operating frequency band of the antenna radiator includes a first frequency band.
