Electronic device and electronic device housing structure

1. An electronic device comprising:

a housing including: a front plate; a rear plate facing a direction opposite a direction faced by the front plate; and a side member formed integrally with the rear plate and surrounding a space between the front plate and the rear plate,

wherein a substantial portion of the rear plate and the side member is formed of an electrically conductive member, and

wherein the rear plate and the side member include:

a slit extending from a first portion of the side member to a third portion of the side member through a second portion of the rear plate, thereby dividing the substantial portion of the rear plate and the side member into two portions, and

an insulating material filling the slit;

a display exposed through the front plate;

a polymer structure positioned to contact with at least one portion of the first portion, at least a portion of the second portion, and at least a portion of the slit; and

at least one conductive piece at least partially embedded on the polymer structure.

2. The electronic device of claim 1 , wherein the polymer structure is formed of a same material as the insulating material.

3. The electronic device of claim 2 , wherein the polymer structure is formed integrally with the insulating material.

4. The electronic device of claim 1 , wherein the at least one conductive piece is formed of a same material as the electrically conductive material.

5. The electronic device of claim 4 , wherein the at least one conductive piece includes aluminum.

6. The electronic device of claim 1 , wherein a maximum thickness of the side member in a direction perpendicular to the rear plate is equal to a maximum thickness of the rear plate.

7. The electronic device of claim 6 , wherein the maximum thickness of the side member in the direction perpendicular to the rear plate is equal to or less than 1.2 mm.

8. The electronic device of claim 1 , further comprising:

a wireless communication circuit electrically connected to a point of the side member adjacent to the first portion or the second portion.

9. The electronic device of claim 1 , wherein the at least one conductive piece is separated from the side member and the rear plate.

10. The electronic device of claim 1 , wherein at least one of the two portions divided from the substantial portion functions as an antenna.

11. The electronic device of claim 1 , wherein the conductive piece is spaced apart from the side member by a predetermined distance.

12. The electronic device of claim 1 , wherein the conductive piece has a groove into which the polymer member is insertable.

13. The electronic device of claim 12 , wherein the groove is formed to extend to the outer surface of the side member.

14. The electronic device of claim 1 , wherein the conductive piece is formed by removing at least a portion of a hemming structure integrally extending and bent from the side member.

15. The electronic device of claim 1 , wherein the side member includes:

a first electrically conductive member including a first electrically conductive material;

a second electrically conductive member including the first electrically conductive material, and electrically insulated from the first electrically conductive member;

a third electrically conductive member disposed in the space, and disposed to face at least one of the first electrically conductive member or the second electrically conductive member; and

wherein the polymer structure is disposed adjacent to the first electrically conductive material, the second electrically conductive member, and the third electrically conductive member.
