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

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 one 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; a third slot disposed on the metal rear cover wherein the second slot is located on one side of the first slot, wherein one end of the second slot connects with the first slot, wherein the third slot is located on another side of the first slot, wherein one end of the third slot connects with the first slot, wherein the metal rear cover comprises a rear cover 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, wherein the antenna part comprises 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, and 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.

2 . The mobile terminal with the new type of antenna structure according to claim 1 , further comprising an antenna extension part, wherein the antenna extension part is connected to the first antenna part.

3 . The mobile terminal with the new type of antenna structure according to claim 2 , wherein the first antenna part is connected to the antenna extension part using a spring plate or an elastic ejector pin.

4 . The mobile terminal with the new type of antenna structure according to claim 2 , wherein the antenna feed point is disposed on the first antenna part, and wherein one end of the antenna extension part is connected to the first antenna part.

5 . The mobile terminal with the new type of antenna structure according to claim 4 , wherein the antenna extension part is connected to a conductor inside the mobile terminal.

6 . The mobile terminal with the new type of antenna structure according to claim 5 , wherein one end of the first slot connects with a bottom of the metal rear cover.

7 . The mobile terminal with the new type of antenna structure according to claim 5 , wherein the first slot, the second slot, and the third slot form a T-shaped slot.

8 . The mobile terminal with the new type of antenna structure according to claim 1 , wherein outline dimensions of the rear cover are greater than an outline dimensions of the first antenna part and an outline dimensions of the second antenna part.

9 . The mobile terminal with the new type of antenna structure according to claim 5 , wherein the first antenna part has a connection point near the first slot, wherein one 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.

10 . The mobile terminal with the new type of antenna structure according to claim 9 , wherein a path from the first antenna part and the connection point to the antenna extension part is a first antenna path, wherein a 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 is a second antenna path, wherein a fundamental mode and a higher order mode of a first 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.
