Abstract

A mobile terminal includes a housing having a front side, a rear side, and lateral sides, and including a metal rim formed of a metal material and at least one bending portion formed of a non-metal material. The mobile terminal includes a rear cover disposed on the rear side of the housing, a reflection sheet disposed on the cover and formed of a metal material, and an antenna module disposed between the rear cover and a front cover of the housing and configured to radiate a beamforming wireless signal, wherein a bending portion of the cover and a flat portion of the cover are configured to include a first region, a second region, and a third region, and a beamforming wireless signal of the first region may be reflected at the second region and the third region by the reflection sheet.

First claim

The invention claimed is:

1. A mobile terminal having a front surface, a rear surface and side surfaces, the mobile terminal comprising:
a housing having a front side, a rear side and lateral sides, the housing including a metal rim formed of a metal material and at least one bending portion formed of a non-metal material, and the lateral side of the housing having two short sides and two long sides that are longer than the two short sides;
a rear cover disposed on the rear side of the housing, the cover having a planar portion and at least one bending portion bent from the planar portion;
a reflection sheet disposed on the cover and formed of a metal material; and
an antenna module disposed between a rear side of the housing and a front cover, and configured to radiate a beamforming radio signal,
wherein the antenna module comprises an insulating member, an electronic element disposed on a surface of the insulating member, and antenna patterns disposed on the other surface of the insulating member,
wherein the antenna module is tilted from a portion of the rear side of the housing, and a side surface shape of the mobile terminal is defined by the bending portion of the cover and a lateral side of the housing,
wherein the bending portion of the cover and the planar portion of the cover comprise a first region, a second region, and a third region,
wherein the second region is disposed to face the antenna patterns, the third region is connected to a portion of the second region adjacent to a side surface portion of the housing, the first region is connected another region of the second region opposite to the third region, and the reflection sheet is disposed on the first region of the cover, and
wherein the beamforming radio signal of the first region is reflected from the second region and the third region by the reflection sheet.

2. The mobile terminal of claim 1 , wherein as the antenna module is tilted, a first edge of a front surface of the antenna module adjacent to the side surface is disposed closer to a rear case than a second edge thereof, and a third edge of a rear surface of the antenna module is configured to be farther from an inside of a front housing than a fourth edge thereof.

3. The mobile terminal of claim 1 , wherein the antenna module further comprises a module mounting portion disposed to surround a rear surface and a side surface of the antenna module, and
wherein the module mounting portion is formed of a metal material to transmit heat generated from the antenna module to the housing formed of a metal material.

4. The mobile terminal of claim 1 , wherein an end portion of each antenna element of the antenna module is extended to form a first line and the other end portion of the antenna element is extended to form a second line,
wherein the rear cover comprises:
the first region disposed to correspond to the planar portion in a direction in which the planar portion is disposed from the first line;
the second region disposed to correspond to a region overlapping the antenna element of the antenna module between the first line and the second line; and
the third region corresponding to a side edge of the rear cover from the second line.

5. The mobile terminal of claim 4 , wherein the reflection sheet is disposed to be spaced apart from the first line by a distance of 1.0 mm or less in the first region of the rear cover.

6. The mobile terminal of claim 5 , wherein the beamforming radio signal radiated from the antenna module is radiated through a second region of the rear cover overlapping the antenna module, and blocked in a first region of the rear cover where the reflection sheet is disposed.

7. The mobile terminal of claim 1 , wherein the reflection sheet is configured with a metal sheet formed of metal material, wherein the metal sheet comprises: a first metal sheet configured to have a first length and a first width to reflect beams emitted from a plurality of antenna elements; and
a second metal sheet configured to extend from the first metal sheet and extend into an inner region of the mobile terminal to operate as a heat dissipation sheet that absorbs heat inside the mobile terminal;
wherein the second metal sheet is configured to have a second length and a second width.

8. The mobile terminal of claim 7 , wherein the first width and the position of an end portion of the first metal sheet are determined such that an extension line formed in a direction perpendicular to the antenna module from one end portion of the antenna element corresponds to the end portion of the first metal sheet or intersects the first metal sheet.

9. The mobile terminal of claim 7 , wherein the first width and the position of an end portion of the first metal sheet are determined such that an extension line formed in a direction perpendicular to the antenna module from one end portion of the antenna element is spaced apart by a minimum separation distance or more from the end portion of the first metal sheet.

10. A mobile terminal having a front surface, a rear surface and side surfaces, the mobile terminal comprising:
a housing having a front side, a rear side and lateral sides, the housing including a metal rim formed of a metal material and at least one bending portion formed of a non-metal material, and the lateral side of the housing having two short sides and two long sides that are longer than the two short sides;
a rear cover disposed on the rear side of the housing, the cover having a planar portion and at least one bending portion bent from the planar portion;
a reflection sheet disposed on the cover and formed of a metal material;
an antenna module disposed between a rear side of the housing and a front cover, and configured to radiate a beamforming radio signal; and
an antenna frame configured to support the antenna module and formed of a metal material,
wherein the antenna module comprises an insulating member, an electronic element disposed on a surface of the insulating member, and antenna patterns disposed on the other surface of the insulating member,
wherein the antenna module is tilted from a portion of the rear side of the housing, and a side surface shape of the mobile terminal is defined by the bending portion of the cover and a lateral side of the housing,
wherein the bending portion of the cover and the planar portion of the cover comprise a first region, a second region, and a third region,
wherein the second region is disposed to face the antenna patterns, the third region is connected to a portion of the second region adjacent to a side surface portion of the housing, the first region is connected another region of the second region opposite to the third region, and the reflection sheet is disposed on the first region of the cover, and
