Abstract

Disclosed is an electronic device may include a housing including a plate including a first surface, and a support bracket including a (1-1)th side wall extending from an edge of the first surface and a (1-2)th side wall separated from the (1-1)th side wall by a first segmented portion, a camera bracket electrically connected to the (1-2)th side wall of the housing, and a printed circuit board disposed within the housing. An antenna pattern provided on the support bracket may include a conductive portion forming at least a portion of the (1-1)th side wall, and a ground portion connected to the conductive portion may be located between the camera bracket and the first segmented portion.

First claim

What is claimed is:

1. An electronic device comprising:
a housing including a plate having a first surface, and a support bracket including a (1-1) th side wall extending from an edge of the first surface and a (1-2) th side wall separated from the (1-1) th side wall by a first segmented portion;
a camera bracket connected to the (1-2) th side wall of the housing; and
a printed circuit board (PCB) disposed within the housing,
wherein an antenna pattern formed on the support bracket includes a conductive portion forming at least a portion of the (1-1) th side wall,
wherein a ground portion connected to the conductive portion is located adjacent to the first segmented portion, and the ground portion is disposed between the camera bracket and the first segmented portion to electrically separate the conductive portion and the camera bracket,
wherein a feeding part is electrically connected to the PCB and the conductive portion, and
wherein the first segmented portion is located between the feeding part and the ground portion.

2. The electronic device of claim 1 ,
wherein the feeding part extends into the housing from the (1-1) th side wall of the support bracket and electrically connected to the PCB.

3. The electronic device of claim 2 , wherein the first segmented portion includes an insulative material having a dielectric constant different from that of the conductive portion.

4. The electronic device of claim 2 , wherein the first segmented portion prevents a current transmitted from the feeding part from being directed to the camera bracket.

5. The electronic device of claim 2 , wherein the first segmented portion is disposed at one end of the conductive portion, and a second segmented portion is disposed on another end of the conductive portion, and
wherein the second segmented portion is located on a same line as the (1-1) th side wall of the support bracket or on a same line as a second side wall perpendicular to the (1-1) th side wall.

6. The electronic device of claim 2 , wherein the ground portion is disposed to be spaced apart, by a second distance, from a first portion on the (1-2) th side wall toward the (1-1) th side wall.

7. The electronic device of claim 6 ,
wherein the first segmented portion is disposed to be spaced apart, by a first distance, from the a first portion toward the (1-1) th side wall, and
wherein the first distance is greater than the second distance.

8. The electronic device of claim 2 , wherein the conductive portion is disposed to be spaced apart, by a first predetermined distance toward the (1-1) th side wall, from a first portion on the (1-2) th side wall, which extends from an edge surface of the camera bracket, and
wherein the ground portion is disposed to be spaced apart from the first portion toward the segmented portion.

9. The electronic device of claim 8 , wherein the ground portion is configured to electrically separate the (1-1) th side wall and the (1-2) th side wall.

10. The electronic device of claim 8 , wherein the ground portion and the PCB are electrically connected to each other by a conductive member.

11. The electronic device of claim 2 , further comprising:
a first ground portion disposed between the first segmented portion and the feeding part when viewed toward the (1-1) th side wall of the support bracket, and configured to change an impedance for adjusting a frequency band.

12. The electronic device of claim 6 , wherein the ground portion or the first ground part is electrically connected to the PCB.

13. The electronic device of claim 2 , further comprising:
an antenna structure,
wherein the ground portion, the first segmented portion, the first ground portion, and the feeding portion are sequentially arranged from a first portion on the (1-2) th side wall extending from an edge surface of the camera bracket toward the (1-1) th side wall to be spaced apart from each other.

14. The electronic device of claim 2 , wherein the housing includes a recess structure, wherein the recess structure includes an opening in which at least a portion of a lens assembly of the camera module is located and an edge portion provided along the periphery of the opening, and
wherein the edge portion is provided integrally with the plate.

15. The electronic device of claim 14 , further comprising:
a waterproof member disposed on one surface of the recess structure that is oriented in the first direction;
the camera bracket stacked with the waterproof member;
a lens protection member disposed on one surface of the recess structure that is oriented in the second direction;
a support member stacked with the lens protection member; and
an elastic member bonded to the support member.

16. The electronic device of claim 2 , wherein the housing includes a recess structure that is provided integrally with the support bracket.

17. An electronic device comprising:
a rear plate disposed to cover a rear surface of the electronic device and including a recess structure provided in an edge area;
a camera bracket disposed along the recess structure and at least partially exposed outward;
a support bracket including a first side wall connected to the rear plate and a second side wall separated from the first side wall and connected to the camera bracket; and
an antenna pattern formed on the support bracket and including a conductive portion forming at least a portion of the first side wall,
wherein at least one segmented portion located at one end of the conductive portion is spaced apart, by a first distance, toward the first side wall, from a first portion on the second side wall extending from the edge surface of the camera bracket,
wherein a ground portion connected to the conductive portion is located adjacent to the at least one segmented portion, and the ground portion is disposed between the camera bracket and the at least one segmented portion to electrically separate the conductive portion and the camera bracket,
wherein a feeding part is electrically connected to a printed circuit board (PCB) and the conductive portion, and
wherein the at least one segmented portion is located between the feeding part and the ground portion.

18. The electronic device of claim 17 ,
wherein the feeding part extends to an inside of the electronic device from the first side wall of the support bracket.

19. The electronic device of claim 18 , wherein the ground portion is spaced apart from the first portion toward the segmented portion.
