Abstract

A terminal device includes a metal frame having at least two slots disposed on a side of the metal frame. At least two antenna feedpoints are disposed on an inner side wall of the metal frame, and different antenna feedpoints in the at least two antenna feedpoints are disposed on side edges of different slots. A signal reflection wall is further provided inside the terminal device, and a gap exists between the signal reflection wall and the at least two slots. The signal reflection wall is formed by a metal wall of a battery chamber of the terminal device, and the battery chamber is a structure that accommodates a battery of the terminal device. The metal frame and the signal reflection wall are both electrically connected to a ground plate of the terminal device.
