Abstract

A terminal device includes a metal frame. At least two slots are 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 located on side edges of different slots. A signal reflection wall is further disposed 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 outer wall of 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.

First claim

What is claimed is:

1. A terminal device, comprising:
a metal frame having at least two slots disposed in a side of the metal frame, at least two antenna feedpoints being disposed on an inner side wall of the metal frame, and different antenna feedpoints in the at least two antenna feedpoints being located on side edges of different slots; and
a signal reflection wall disposed inside the terminal device, a gap existing between the signal reflection wall and the at least two slots, and the signal reflection wall being formed by a metal outer wall of a battery of the terminal device; wherein
the metal outer wall is a metal sidewall of the battery proximate to the side of the metal frame in which the at least two slots are located, and the metal sidewall is a metal layer coating on a surface of the battery;
the metal frame and the signal reflection wall are both electrically connected to a ground plate of the terminal device; and
each slot of the at least two slots is disposed opposite to the signal reflection wall.

2. The terminal device according to claim 1 , wherein an antenna feedpoint is located at a non-central position of a side edge of each slot.

3. The terminal device according to claim 1 , wherein each slot is a rectangular slot, and the slot and the metal frame have a same length direction.

4. The terminal device according to claim 1 , wherein the at least two slots are arranged along a length direction of the metal frame.

5. The terminal device according to claim 4 , wherein each of the slots has a same length, and there is a same distance between any two adjacent slots.

6. The terminal device according to claim 4 , wherein a distance between two adjacent slots is determined by an isolation between two adjacent antennas and a beam scanning coverage angle of an antenna array.

7. The terminal device according to claim 4 , wherein an upper edge of the signal reflection wall is not lower than upper edges of the at least two slots, and a lower edge of the signal reflection wall is not higher than lower edges of the at least two slots.

8. The terminal device according to claim 1 , wherein at least two slots are provided in each of two opposite sides of the metal frame; and
two opposite metal sidewalls of the battery proximate to the two opposite sides of the metal frame act as two signal reflection walls of slots disposed in the two opposite sides.

9. The terminal device according to claim 1 , wherein each slot is a cross-shaped slot or an I-shaped slot.

10. The terminal device according to claim 1 , wherein a length of each slot is determined according to a half wavelength corresponding to a center frequency of an operating frequency band of an antenna.

11. The terminal device according to claim 1 , wherein the signal reflection wall is a concave reflection curved surface; or the signal reflection wall is a convex reflection curved surface.
