Abstract

A mobile terminal includes an external interface body, an antenna assembly, and a first filter unit. The antenna assembly includes a first antenna, a second antenna, and a diplexer. The external interface body is disposed in an antenna clearance area defined by the first antenna and the second antenna. The diplexer is connected to the first antenna, the second antenna, and a feed of a board of the mobile terminal. The first filter unit is disposed between the first antenna and the external interface body and is connected to a first circuit board of the external interface body to reduce interference from the external interface body to the antenna assembly.

First claim

What is claimed is:

1. A mobile terminal, comprising:
an external interface body;
an antenna assembly, comprising:
a first antenna and a second antenna, wherein the external interface body is disposed in an antenna clearance area defined by the first antenna and the second antenna; and
a diplexer connected to the first antenna, the second antenna, and a feed of a board of the mobile terminal; and

a first filter unit disposed between the first antenna and the external interface body, wherein the first filter unit is connected to a first circuit board of the external interface body to reduce interference from the external interface body to the antenna assembly; and
a second filter unit;
wherein the external interface body is an earphone socket, the first antenna is disposed on a side of the earphone socket and the second antenna is disposed on another side of the earphone socket, and the second filter unit is disposed between the second antenna and the earphone socket and is connected to a second circuit board of the earphone socket to reduce interference from the earphone socket to the antenna assembly.

2. The mobile terminal as claimed in claim 1 , wherein the first circuit board is disposed between the first antenna and the external body.

3. The mobile terminal as claimed in claim 1 , wherein the second circuit board is disposed between the second antenna and the earphone socket.

4. The mobile terminal as claimed in claim 3 , wherein when the diplexer and the external interface body are arranged at a bottom side of the mobile terminal, the diplexer is further away from the bottom side than the external interface body; and when the diplexer and the external interface body are arranged at a top side of the mobile terminal, the diplexer is further away from the top side than the external interface body.

5. The mobile terminal as claimed in claim 1 , wherein the first antenna is a low frequency antenna and the second antenna is a mid-high frequency antenna.

6. The mobile terminal as claimed in claim 1 , further comprising a fingerprint assembly, wherein the first antenna is disposed between the fingerprint assembly and the earphone socket.

7. The mobile terminal as claimed in claim 1 , wherein the first filter unit is connected to a ground of the board.

8. The mobile terminal as claimed in claim 1 , wherein the second filter unit is connected to a ground of the board.

9. The mobile terminal as claimed in claim 1 , wherein a frequency range of the first antenna is in a range of 824 MHz to 960 MHz, and a frequency range of the second antenna is in a range of 1710 MHz to 2690 MHz.

10. The mobile terminal as claimed in claim 1 , wherein when the diplexer and the external interface body are arranged at a bottom side of the mobile terminal, the diplexer is further away from the bottom side than the external interface body; and when the diplexer and the external interface body are arranged at a top side of the mobile terminal, the diplexer is further away from the top side than the external interface body.

11. The mobile terminal as claimed in claim 1 , wherein the first circuit board is disposed between the external interface body and the diplexer.

12. The mobile terminal as claimed in claim 1 , wherein the first circuit board is disposed in the antenna clearance area defined by the first antenna and the second antenna and the first circuit board is a microphone pin, a detection pin or a ground pin.

13. The mobile terminal as claimed in claim 1 , wherein the first filter unit comprises a capacitor and an inductor, an end of the inductor is connected to the first circuit board, another end of the inductor is connected to an end of the capacitor, and another end of the capacitor is connected to a ground of the board.

14. The mobile terminal as claimed in claim 1 , further comprising a plurality of filter units, the earphone socket comprising a plurality of pins, a number of the filter units being corresponding to a number of the pins of the earphone socket, and the pins of the earphone socket are disposed in the antenna clearance area.

15. The mobile terminal as claimed in claim 6 , wherein the external interface body is a universal serial bus (USB) interface body, the fingerprint assembly comprises a fingerprint tray, when the USB interface body and the fingerprint tray are arranged at a bottom side of the mobile terminal, the USB interface body is disposed further away from the bottom side than the fingerprint tray.
