Abstract

A mobile terminal is disclosed. The mobile terminal includes a housing with an accommodation space, the housing including a metal rear cover serving as a radiator, the metal rear cover including a first metal part, a second metal part and a third metal part insulated to each other; a mainboard received in the accommodation space, the mainboard including a grounding part and a feed part; an antenna module including a grounding dynamic switch unit and a feed dynamic switch unit; wherein the grounding dynamic switch unit is connected between the grounding part and the first metal part, one end of the feed dynamic switch unit connects with the feed part, and the other end connects with the first metal part or the second metal part selectively.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a housing with an accommodation space, the housing including a metal rear cover serving as a radiator, the metal rear cover including a first metal part, a second metal part and a third metal part insulated to each other;
a mainboard received in the accommodation space, the mainboard including a grounding part and a feed part;
an antenna module, including a grounding dynamic switch unit and a feed dynamic switch unit;
wherein the grounding dynamic switch unit is connected between the grounding part and the first metal part, one end of the feed dynamic switch unit connects with the feed part, and the other end connects with the first metal part or the second metal part selectively.

2. The mobile terminal as described in claim 1 , wherein the feed dynamic switch unit includes a first feed dynamic switch connected with the first metal part electrically and a second feed dynamic switch connected with the second metal part electrically.

3. The mobile terminal as described in claim 1 , wherein the metal rear cover further includes an insulating tape disposed on a junction of the first metal part, the second metal part and the third metal part.

4. The mobile terminal as described in claim 2 , wherein the first metal part is formed by the frame of one side of the metal rear cover and the frame of one section of side with the same length extended from two ends of frame of the side, the second metal part is a rectangular metal sheet of a top surface of the metal rear cover.

5. The mobile terminal as described in claim 4 , wherein the first metal part and the second metal part serve as a radiator of the antenna module.

6. The mobile terminal as described in claim 2 , wherein when the grounding dynamic switch unit and the first feed dynamic switch are on the connected state, the feed terminal is connected with the first metal terminal through the first feed dynamic switch electrically, at this time, the working frequency bands of the antenna module is 824 MHz-960 MHz and 1710 MHz-1880 MHz.

7. The mobile terminal as described in claim 2 , wherein when the grounding dynamic switch unit and the second feed dynamic switch are on connected state, the feed terminal is connected with the second metal terminal through the second feed dynamic switch, at this time the working frequency bands of the antenna module are 1850 MHz-1990 MHz and 1920 MHz-2170 MHz.

8. The mobile terminal as described in claim 2 , wherein when the grounding dynamic switch unit is on disconnected state and the first feed dynamic switch are on the connected state, the feed terminal is connected with the first metal terminal through the first feed dynamic switch electronically, at this time, the working frequency band of the antenna module is 2470 MHz-2690 MHz.

9. The mobile terminal as described in claim 2 , wherein when the grounding dynamic switch unit is on the disconnected state and the second feed dynamic switch is on the connected state and the feed terminal is connected with the second metal terminal through the second feed dynamic switch electronically, at this time the working frequency bands of the antenna module are 1920 MHz-2170 MHz and 2300 MHz-2470 MHz.

10. The mobile terminal as described in claim 1 , wherein the antenna module is an LTE antenna module.
