Abstract

An electronic device is provided. The electronic device includes a housing and an antenna radiator disposed in the housing. An opening is formed in the housing. The opening includes a first portion configured to align with a length direction of the antenna radiator at a position corresponding to the antenna radiator and penetrate the housing in a thickness direction, and a second portion connected to the first portion, the second portion being configured to form a specified angle with respect to the length direction of the antenna radiator and penetrate the housing in a thickness direction. At least a portion of the housing, which surrounds the opening, comprises a conductive member. At least a portion of a circumference of the opening comprises an electrical open curve.

First claim

What is claimed is:

1. An electronic device comprising:
a housing forming an appearance of the electronic device; and
an antenna radiator disposed in an internal space formed by the housing,
wherein an opening is formed in the housing and is spaced a distance apart from a position corresponding to the antenna radiator,
wherein the opening comprises:
a first portion configured to:
align with a length direction of the antenna radiator at a position corresponding to the antenna radiator, and
penetrate the housing in a thickness direction; and

a second portion connected to the first portion, the second portion being configured to:
form a specified angle with respect to the length direction of the antenna radiator, and
penetrate the housing in the thickness direction,

wherein at least a portion of the housing, which surrounds the opening, comprises a conductive member, and
wherein at least a portion of a circumference of the opening comprises an electrical open curve.

2. The electronic device of claim 1 , wherein the opening is at least formed in a rear housing of the electronic device.

3. The electronic device of claim 1 , wherein at least one of the first portion and the second portion is formed to comprise an oblong shape.

4. The electronic device of claim 1 , wherein the first portion is formed in a one of a rear housing, an upper-side housing, and bottom-side housing.

5. The electronic device of claim 1 , wherein the second portion is formed to expand toward one of an upper-side housing and a bottom-side housing of the electronic device.

6. The electronic device of claim 1 , wherein the second portion is formed to expand toward one side periphery of the housing of the electronic device.

7. The electronic device of claim 1 , wherein, when one end of the second portion is connected to the first portion and the second portion is configured to be perpendicular with respect to the first portion, the first portion and the second portion together form a “T” shape.

8. The electronic device of claim 1 , wherein at least a portion of the housing, which is formed of the conductive member, is electromagnetically coupled to the antenna radiator at the circumference of the opening.

9. The electronic device of claim 1 , wherein a length of the electrical open curve is determined based on a specified wavelength.

10. The electronic device of claim 1 , wherein the opening is filled with a dielectric member.

11. An electronic device comprising:
an external housing forming an appearance of the electronic device, and including a first surface and a second surface facing an opposite direction of the first surface;
a conductive member forming at least a portion of the first surface of the external housing;
an antenna radiator disposed in an internal space formed by the external housing and spaced apart from the conductive member; and
an opening formed by penetrating at least a portion of the conductive member,
wherein the opening comprises:
a first portion configured to substantially align with at least a portion of the antenna radiator; and
a second portion configured to be substantially perpendicular to the first portion,

wherein the second portion extends from a portion of the first portion to an adjacency of one of a periphery of the conductive member.

12. The electronic device of claim 11 , wherein the opening is formed to comprise a “T” shape.

13. The electronic device of claim 11 , further comprising a non-conductive material filling at least a portion of the opening.

14. The electronic device of claim 11 , wherein the conductive member is disposed above a battery mounted in the external housing.

15. The electronic device of claim 11 ,
wherein the external housing further comprises a third surface interposed between the first surface and the second surface, and
wherein a portion of a display is disposed on the third surface of the external housing.

16. The electronic device of claim 11 , wherein at least a portion of a display is disposed on at least a portion of the first surface of the external housing.

17. The electronic device of claim 16 , wherein the display is configured to:
pass a third surface to a location between the first surface and the second surface, from the second surface, of the external housing, and
connect to at least the portion of the first surface.

18. The electronic device of claim 17 , wherein the conductive member extends from at least a portion of the first surface of the external housing to at least a portion of the third surface.

19. The electronic device of claim 11 ,
wherein the electronic device further comprises another opening formed by penetrating at least another portion of the conductive member, and
wherein at least one electronic component included in the housing is exposed to the outside through the other opening.

20. The electronic device of claim 11 , wherein the antenna radiator is configured to form at least a portion of an inverted-F antenna.
