Abstract
A handheld device includes a metal frame, two switches, and an antenna feedpoint, where two slits are disposed at the metal frame; the slits divide the metal frame into a left frame, a middle frame, and a right frame; two sides of each slit are bridged by one switch, where one of the switches is in a connected state, the other of the switches is in a disconnected state, and the two switches perform state switching when a user's finger connects a slit corresponding to the switch in a disconnected state; and the antenna feedpoint is electrically connected to the middle frame, and the left frame and the right frame are grounded, to form an antenna.
