Abstract

A terminal device includes a metal frame. At least two slots are provided on one side of the metal frame; at least two antenna feed points are provided on an inner side wall of the metal frame, and different antenna feed points in the at least two antenna feed points are located on sides of different slots. The terminal device is further provided therein with a signal reflecting wall, and there is a gap between the signal reflecting wall and the at least two slots. The signal reflecting wall is formed by a metal wall of a battery compartment of the terminal device, and the signal reflecting wall is a reflective curved surface that is convex. The metal frame and the signal reflecting wall are electrically connected with a ground plate in the terminal device.

First claim

What is claimed is:

1. A terminal device, comprising
a metal frame, and at least two slots are provided in one side of the metal frame;
at least two antenna feed points provided on an inner side wall of the metal frame, and different antenna feed points in the at least two antenna feed points are located on sides of different slots;
a signal reflecting wall, and there is a gap between the signal reflecting wall and the at least two slots; the signal reflecting wall is formed by a metal wall of a battery compartment of the terminal device, and the signal reflecting wall is a reflective curved surface that is convex, wherein the battery compartment is a structure that accommodates a battery of the terminal device; and
the metal frame and the signal reflecting wall are electrically connected to a ground plate in the terminal device.

2. The terminal device according to claim 1 , wherein the reflective curved surface is formed by a bus bar parallel to a length direction of the metal frame; or, the reflective curved surface is formed by a bus bar parallel to a width direction of the metal frame.

3. The terminal device according to claim 2 , wherein the reflective curved surface is a parabolic surface.

4. The terminal device according to claim 1 , wherein an upper edge of the signal reflecting wall is not lower than upper edge of the slots, and a lower edge of the signal reflecting wall is not higher than lower edges of the slots.

5. The terminal device according to claim 1 , wherein the signal reflecting wall includes at least two reflective curved surfaces that are in one-to-one correspondence with positions of the slots.

6. The terminal device according to claim 5 , wherein the at least two slots are arranged along a length direction of the metal frame; each slot is of an equal length, and any two adjacent slots are spaced by an equal distance.

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

8. The terminal device according to claim 1 , wherein a slot includes a first sub-slot and a second sub-slot that intersect.

9. The terminal device according to claim 8 , wherein the signal reflecting wall includes a first reflective curved surface that is convex and corresponds to the first sub-slot, and a second reflective curved surface that is convex and corresponds to the second sub-slot; and a bus bar forming the first reflective curved surface is perpendicular to a bus bar forming the second reflective curved surface.

10. The terminal device according to claim 9 , wherein a long side of the first sub-slot and a long side of the second sub-slot intersect at a right angle.

11. The terminal device according to claim 1 , further comprising at least two slots provided in another side of the metal frame opposite the one side of the metal frame.

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

13. The terminal device according to claim 1 , wherein an antenna feed point is located at a non-central position of an inner side of a slot.

14. The terminal device according to claim 1 , wherein
the metal frame is a radiator of a communication antenna.
