Abstract

An electronic device is provided. The electronic device including a housing comprising a front plate which faces a first direction, a back plate which faces a second direction opposite from the first direction, and a lateral member which surrounds a space between the front plate and the back plate and has at least one part formed from a metal material, a display seen through a first part of the front plate, an antenna module positioned inside the space, and a wireless communication circuit. The antenna module includes a first surface facing a third direction forming an acute angle with the second direction, a second surface facing a fourth direction opposite from the third direction, at least one first conductive element disposed on the first surface or inside the antenna module so as to face the third direction, and at least one second conductive element which is adjacent to the lateral member between the first surface and the second surface and extends in a fifth direction different from the third direction and the fourth direction and facing between the lateral surface and the first part of the front plate.

First claim

What is claimed is:

1. A portable communication device comprising:
a front non-conductive cover including a display area and a non-display area extended from the display area;
a rear non-conductive cover;
a display disposed under the front non-conductive cover;
a housing accommodating the display and forming at least part of a first side portion between the front non-conductive cover and the rear non-conductive cover, the first side portion including a conductive portion forming at least part of a side surface of the portable communication device; and
an antenna module accommodated in the housing as inclined with respect to the rear non-conductive cover, the antenna module configured to radiate a beam at least partially toward the non-display area of the front non-conductive cover.

2. The portable communication device of claim 1 , further comprising:
an antenna support member including a face inclined with respect to the rear non-conductive cover, wherein the antenna module is disposed above the inclined face of the antenna support member.

3. The portable communication device of claim 2 , further comprising:
a heat dissipation member disposed between the antenna module and the antenna support member, and configured to dissipate heat generated from the antenna module.

4. The portable communication device of claim 1 ,
wherein the first side portion includes a non-conductive portion adjacent to the conductive portion, and
wherein the antenna module is configured to radiate the beam partially toward the non-conductive portion of the first side portion such that a first portion of the beam is to be radiated via the non-display area of the front non-conductive cover and a second portion of the beam is to be radiated via the non-conductive portion of the first side portion.

5. The portable communication device of claim 1 ,
wherein the first side portion includes a non-conductive portion adjacent to the conductive portion, and
wherein the antenna module includes a first antenna configured to radiate the beam via the non-display area of the front non-conductive cover and a second antenna configured to radiate another beam via at least one of the non-conductive portion of the first side portion or the rear non-conductive cover.

6. The portable communication device of claim 1 ,
wherein the housing includes a second side portion opposite to the first side portion, and the second side portion includes another conductive portion forming at least part of another side surface of the portable communication device and a non-conductive portion adjacent to the other conductive portion, and
wherein the portable communication device further comprises another antenna module accommodated in the housing and disposed in proximity of the second side portion, and the antenna module includes a plurality of antennas including a first antenna and a second antenna configured, together, to radiate another beam via at least one of a non-conductive portion of the second side portion or the rear non-conductive cover.

7. The portable communication device of claim 6 , wherein the first and second antennas are substantially perpendicular to a planar surface of the rear non-conductive cover such that the another beam is to be radiated via the non-conductive portion of the second side portion.

8. The portable communication device of claim 6 , wherein the first and second antennas are substantially parallel with a planar surface of the rear non-conductive cover such that the another beam is to be radiated via the rear non-conductive cover.

9. The portable communication device of claim 1 , wherein the antenna module includes dipole antennas.

10. The portable communication device of claim 1 , wherein the antenna module is spaced apart from the non-display area of the front non-conductive cover.

11. The portable communication device of claim 1 , wherein the antenna module includes a fastening member configured to fix the antenna module to the housing.

12. A portable communication device comprising:
a front non-conductive cover;
a rear non-conductive cover including a planar surface and a curved surface extended from the planar surface;
a housing including a first side portion, the first side portion including a conductive portion and a non-conductive portion adjacent to the conductive portion;
a printed circuit board disposed in the housing; and
an antenna module disposed in the housing, the antenna module comprising:
a radio frequency (RF) communication module,
a plurality of patch antennas electrically connected to the RF communication module, and is inclined with respect to the planar surface of the rear non-conductive cover, and is configured, together, to radiate a beam toward the curved surface of the rear non-conductive cover or the non-conductive portion, and
a flexible circuit board including a first area in which the RF communication module is located, a second area in which a connector for connecting to the printed circuit board is located, and a bridge area extending from the first area to the second area.

13. The portable communication device of claim 12 , wherein the flexible circuit board includes a first surface and a second surface opposite to the first surface, the RF communication module is located at the first surface, and the connector is located at the second surface.

14. The portable communication device of claim 12 , further comprising:
a battery disposed in the housing,
wherein at least a portion of the antenna module is disposed in proximity of the battery, and
wherein at least a portion of the bridge area of the flexible circuit board is disposed to extend toward the printed circuit board along an upper surface or a lower surface of the battery.

15. The portable communication device of claim 12 , further comprising:
an antenna support member including a face inclined with respect to the rear non-conductive cover, wherein the antenna module is disposed above the inclined face of the antenna support member.

16. The portable communication device of claim 15 , wherein the antenna support member includes a recess formed at an end of the antenna housing to provide a passage through which the flexible circuit board of the antenna module extends to the printed circuit board.

17. The portable communication device of claim 16 , wherein the recess includes a plurality of openings.
