Abstract

A mobile terminal includes a terminal body, an antenna module coupled to the terminal body and including a radiator for transmitting and receiving radio signals, a circuit board electrically coupled to the antenna module for processing the transmitted and received radio signals, and at least one coupling member positioned proximate to and spaced from the radiator a particular distance for coupling the antenna module to the terminal body. The at least one coupling member is coupled to the radiator.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a terminal body;
an antenna module coupled to the terminal body, the antenna module comprising a carrier positioned proximate to a first end of the terminal body and a radiator positioned on at least a first surface of the carrier and configured for transmitting and receiving radio signals;
a circuit board electrically coupled to the antenna module and configured to process the transmitted and received radio signals; and
at least one coupling member electrically coupled to the radiator and configured for coupling the antenna module to the terminal body,
wherein the carrier comprises at least one opening,
wherein each of the at least one coupling member is inserted into a corresponding opening of the at least one opening and coupled to the terminal body so as to fix the antenna module to the terminal body, and
wherein the at least one coupling member is positioned proximate to the radiator at a particular distance so as to be electrically coupled to the radiator.

2. The mobile terminal of claim, wherein the at least one coupling member extends through the carrier from the first surface to a second surface opposite the first surface.

3. The mobile terminal of claim 1 , wherein:
the opening comprising:
a recess in the first surface having a depth less than a thickness of the carrier, the thickness of the carrier measured from the first surface to a second surface of the carrier opposite the first surface; and
an aperture extending from a bottom surface of the recess to the second surface of the carrier; and
each of the at least one coupling member comprises a head portion positioned in the recess of a corresponding opening of the at least one opening, a bottom surface of the head portion configured to couple with the bottom surface of the recess, and a body portion positioned in the aperture of the corresponding opening; and
the body portion of the at least one coupling member is configured to couple with the terminal body.

4. The mobile terminal of claim 3 , wherein at least a portion of the radiator surrounds at least a portion of a perimeter of the recess of an opening of the at least one opening.

5. The mobile terminal of claim 3 , further comprising:
a connector portion positioned at the first end of the terminal body and electrically coupled to the circuit board, the connector portion comprising a terminal configured for electrically coupling with a connector of an external device,
wherein the carrier is positioned to cover the connector portion such that the connector portion is positioned between the carrier and the terminal body, and
the carrier applies pressure to the connector portion to restrict movement of the connector portion.

6. The mobile terminal of claim 5 , wherein the at least one coupling member is configured to increase the pressure applied by the carrier to the connector portion when pressure applied by the bottom surface of the at least one coupling member against the bottom surface of the recess of the corresponding opening is increased.

7. The mobile terminal of claim 5 , wherein:
the at least one coupling member comprises a first screw and a second screw;
the first screw is positioned proximate a first side of the connector portion; and
the second screw is positioned proximate a second side of the connector portion.

8. The mobile terminal of claim 1 , wherein at least a portion of the radiator comprises a varying width for transmitting and receiving radio signals on different frequency bands.

9. The mobile terminal of claim 8 , wherein:
the at least one coupling member comprises a first screw and a second screw; and
the first screw and the second screw are spaced apart from each other.

10. The mobile terminal of claim 9 , wherein:
the first screw is configured to resonate at a high frequency band of the different frequency bands; and
the second screw is configured to resonate at a low frequency band of the different frequency bands.

11. The mobile terminal of claim 1 , wherein:
the terminal body comprises a case formed of a dielectric material;
the case forms an outer appearance of the terminal body; and
the at least one coupling member is coupled to the case.

12. The mobile terminal of claim 1 , wherein the particular distance is 3.0 mm or less.

13. The mobile terminal of claim 1 , wherein:
the at least one coupling member is coupled to the radiator and is further configured to change a resonance frequency of the antenna module.

14. The mobile terminal of claim 3 , wherein:
the radiator is further positioned in at least a portion of an opening of the at least one opening to surround at least a portion of a coupling member of the at least one coupling member.

15. The mobile terminal of claim 1 , wherein a transmission frequency of the radiator includes a frequency band corresponding to a personal communication system (PCS), an advanced wireless service (AWS), a digital communications network (DCN), or a long term evolution (LTE).

16. The mobile terminal of claim 1 , further comprising:
a speaker positioned within an inner space of the carrier,
wherein the inner space of the carrier is configured to resonate sound output from the speaker.

17. The mobile terminal of claim 16 , wherein the carrier comprises:
a first region on which the radiator is patterned, the first region comprising at least one portion of the inner space; and
a second region spaced from the first region, and on which the speaker is arranged.

18. The mobile terminal of claim 17 , wherein:
the first region of the carrier extends in a lateral direction of the terminal body proximate the first end of the terminal body, and
the second region of the carrier extends along a first side of the terminal body and away from the first end of the terminal body.
