Abstract

A mobile terminal with a antenna structure applicable to the field of communications equipment technologies, where the antenna structure includes a metal rear cover, a first slot which is disposed on the metal rear cover, and connects with the metal rear cover through one end, a second slot and a third slot which are disposed on the metal rear cover, and located on opposite sides of the first slot, and connects with the first slot through one end, and the metal rear cover includes a rear cover which is located on one side of the second slot and the third slot, and an antenna part located on the other side of the second slot and the third slot, and the antenna part includes a first antenna part located on one side of the first slot and a second antenna part located on the other side of the first slot.

First claim

What is claimed is:

1. A mobile terminal with a new type of antenna structure, wherein the antenna structure comprises:
a metal rear cover;
a first slot disposed on the metal rear cover, wherein a first end of the first slot connects with a lateral face or an end face of the metal rear cover;
a second slot disposed on the metal rear cover, wherein the second slot is located on a first side of the first slot, and wherein a first end of the second slot connects with a second end of the first slot;
a third slot disposed on the metal rear cover, wherein the third slot is located on a second side of the first slot, and wherein a first end of the third slot connects with the second end of the first slot,
wherein the metal rear cover comprises:
a rear cover located adjacent to a first side of the second slot and a first side of the third slot;
a first antenna part located adjacent to the first side of the first slot and a second side of the second slot; and
a second antenna part located adjacent to the second side of the first slot and a second side of the second slot,
wherein both the first antenna part and the second antenna part are integrally connected to the rear cover; and

an antenna feed point disposed on the first antenna part and/or the second antenna part, wherein the antenna feed point is connected to a transceiver of the mobile terminal using a feeder; and
an antenna extension part connected to the first antenna part, wherein the first antenna part is connected to the antenna extension part using a spring plate or an elastic ejector pin.

2. The mobile terminal of claim 1 , wherein the antenna feed point is disposed on the first antenna part, and wherein a first end of the antenna extension part is connected to the first antenna part.

3. The mobile terminal of claim 2 , wherein the antenna extension part is connected to a conductor inside the mobile terminal.

4. The mobile terminal of claim 3 , wherein the first end of the first slot connects with a bottom of the metal rear cover.

5. The mobile terminal of claim 3 , wherein the first slot, the second slot, and the third slot form a T-shaped slot.

6. The mobile terminal of claim 3 , wherein the first antenna part comprises a connection point, wherein the first end of the antenna extension part is connected to the connection point, and wherein the antenna extension part comprises:
a first extension part that extends in a direction of the rear cover;
a second extension part that extends in a direction leaving the first slot from a tail end of the first extension part;
a third extension part that extends in a direction opposite to the rear cover from a tail end of the second extension part; and
a fourth extension part that extends in a direction approaching the first slot from a tail end of the third extension part.

7. The mobile terminal of claim 6 , further comprising:
a first antenna path from the first antenna part via the connection point to the antenna extension part; and
a second antenna path from a joint between the second antenna part and the rear cover to an opposite direction of the rear cover and a direction of the first slot,
wherein a fundamental mode and a higher order mode of the first antenna path form a low-frequency resonance and a first high-frequency resonance respectively, wherein a space coupling exists between the second antenna path and the first antenna path, and wherein the second antenna path is excited to form a second high-frequency resonance.

8. The mobile terminal of claim 1 , wherein an area of the rear cover is greater than an area of the first antenna part and an area of the second antenna part.

9. A mobile terminal with a new type of antenna structure, wherein the antenna structure comprises:
a metal rear cover;
a first slot disposed on the metal rear cover, wherein a first end of the first slot connects with a lateral face or an end face of the metal rear cover;
a second slot disposed on the metal rear cover wherein the second slot is located on a first side of the first slot, and wherein a first end of the second slot connects with a second end of the first slot;
a third slot disposed on the metal rear cover, wherein the third slot is located on a second side of the first slot, and wherein a first end of the third slot connects with the second end of the first slot,
wherein the metal rear cover comprises:
a rear cover located adjacent to a first side of the second slot and a first side of the third slot;
a first antenna part located adjacent to the first side of the first slot and a second side of the second slot, wherein the first antenna part comprises a connection point; and
a second antenna part located adjacent to the second side of the first slot and a second side of the second slot, and
wherein both the first antenna part and the second antenna part are integrally connected to the rear cover;

an antenna feed point disposed on the first antenna part, wherein the antenna feed point is connected to a transceiver of the mobile terminal using a feeder; and
an antenna extension part, wherein a first end of the antenna extension part is connected to the connection point, wherein the antenna extension part is connected to a conductor inside the mobile terminal, and wherein the antenna extension part comprises:
a first extension part that extends in a direction of the rear cover;
a second extension part that extends in a direction leaving the first slot from a tail end of the first extension part;
a third extension part that extends in a direction opposite to the rear cover from a tail end of the second extension part; and
a fourth extension part that extends in a direction approaching the first slot from a tail end of the third extension part.

10. The mobile terminal of claim 9 , wherein the first antenna part is connected to the antenna extension part using a spring plate or an elastic ejector pin.

11. The mobile terminal of claim 9 , wherein the first end of the first slot connects with a bottom of the metal rear cover.

12. The mobile terminal of claim 9 , wherein the first slot, the second slot, and the third slot form a T-shaped slot.

13. The mobile terminal of claim 9 , wherein an area of the rear cover is greater than an area of the first antenna part and an area of the second antenna part.
