Abstract

An antenna of a terminal device, the antenna includes a metal frame, a side of the metal frame is provided with at least two slot units, each slot unit includes a first slot ring and a second slot ring, the first slot ring and the second slot ring communicate through a third slot, an outer edge circumference of the first slot ring is different from that of the second slot ring. Portions of the metal frame on both sides of the third slot are provided with an antenna feed point and a ground feed point, respectively. The metal frame is electrically connected with a ground plate in the terminal device.

First claim

What is claimed is:

1. An antenna of a terminal device, the antenna comprising:
a metal frame, wherein a side of the metal frame is provided with at least two slot units, each slot unit comprises a first slot ring and a second slot ring, the first slot ring and the second slot ring communicate through a third slot, and an outer edge circumference of the first slot ring is different from an outer edge circumference of the second slot ring;
portions of the metal frame on both sides of the third slot are provided with an antenna feed point and a ground feed point, respectively; and
the metal frame is electrically connected with a ground plate in the terminal device.

2. The antenna of the terminal device according to claim 1 , wherein an inner edge circumference of the first slot ring is different from an inner edge circumference of the second slot ring.

3. The antenna of the terminal device according to claim 1 , wherein any antenna feed point and ground feed point are located on an inner side wall of the metal frame.

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

5. The antenna of the terminal device according to claim 1 , wherein spacing between two adjacent slot units is determined by isolation between the two adjacent slot units and performance of a beam scanning coverage angle of an array antenna.

6. The antenna of the terminal device according to claim 1 , wherein spacing between any two adjacent slot units is a same.

7. The antenna of the terminal device according to claim 1 , wherein both the first slot ring and the second slot ring are circular slots, a width of the third slot is less than an inner radius of the first slot ring, and less than an inner radius of the second slot ring.

8. The antenna of the terminal device according to claim 7 , wherein distances between at least two consecutive points on an upper edge of each slot unit and an upper edge of the metal frame are a first constant value; and/or distances between at least two consecutive points on a lower edge of each slot unit and a lower edge of the metal frame are a second constant value.

9. The antenna of the terminal device according to claim 1 , wherein each slot unit of the at least two slot units and a third slot corresponding to the slot unit are filled with a non-conductive material.

10. The antenna of the terminal device according to claim 1 , wherein both the first slot ring and the second slot ring are rectangular ring-shaped slots, a position communicating the third slot with the first slot ring is located at a midpoint of the outer side of the first slot ring, and a position communicating the third slot with the second slot ring is located at a midpoint of the outer side of the second slot ring.

11. The antenna of the terminal device according to claim 10 , wherein a length direction of the first slot ring and/or a length direction of the second slot ring are consistent with a length direction of the metal frame.

12. The antenna of the terminal device according to claim 1 , wherein both the first slot ring and the second slot ring are rhombus ring-shaped slots, a position communicating the third slot with the first slot ring is located at a corner of a rhombus formed by the first slot ring, and a position communicating the third slot with the second slot ring is located at a corner of a rhombus formed by the second slot ring.

13. The antenna of the terminal device according to claim 12 , wherein in two diagonal lines of the rhombus formed by the first slot ring, a length of a diagonal line parallel to a length direction of the metal frame is longer than a length of a diagonal line parallel to a width direction of the metal frame; and/or,
in two diagonal lines of the rhombus formed by the second slot ring, a length of a diagonal line parallel to a length direction of the metal frame is longer than a length of a diagonal line parallel to a width direction of the metal frame.

14. The antenna of the terminal device according to claim 12 , wherein the rhombus formed by the first slot ring is similar or dissimilar to the rhombus formed by the second slot ring.
