Abstract

An electronic device includes a housing including a first plate, a second plate, and a side member including a first conductive member and a second conductive member which surround a space between the first plate and the second plate and are separated from each other by a slit, a support member interposed in a space between the first plate and the second plate, a PCB, a wireless communication circuit disposed on the PCB, a display, a connection part protruding toward an inner part of the housing from an area of the second conductive member that is adjacent to the slit, the connection part being electrically connected with the second conductive member, and a coupling member coupled to the connection part. The wireless communication circuit is configured to electrically connect the second conductive member and the connection part with an antenna circuit provided on the PCB.

First claim

What is claimed is:

1. An electronic device comprising:
a housing including a first plate, which faces a first direction, a second plate which faces a second direction opposite to the first direction, and a side member including a first conductive member and a second conductive member which substantially surrounds a space between the first plate and the second plate and are separated from each other by a slit;
a support member interposed between the first plate and the second plate;
a printed circuit board (PCB) disposed on a first surface of the support member;
a display disposed on a second surface of the support member, the display facing a direction opposite to a direction of the first surface of the support member, and the display being exposed through at least a portion of the first plate;
wherein the second conductive member includes a connection portion protruding toward an inner part of the housing from an area of the second conductive member that is adjacent to the slit, the connection portion being electrically connected with the second conductive member; and
a coupling member coupled to the connection portion,
wherein a wireless communication circuit provided on the PCB is electrically connected to the first conductive member and to the second conductive member through the connection portion, and
wherein the first conductive member at least partially forms an antenna with the second conductive member.

2. The electronic device of claim 1 , wherein a pad including a copper (Cu) pattern is formed on at least a portion of an area of the PCB that makes contact with the connection portion.

3. The electronic device of claim 1 wherein an anodizing film area is included on at least a portion of a surface of the connection portion.

4. The electronic device of claim 3 , wherein the connection portion operates as a floating ground.

5. The electronic device of claim 1 , wherein the coupling member is a screw and is screw-tightened with the connection portion.

6. The electronic device of claim 1 ,
wherein the wireless communication circuit includes a first matching circuit electrically connected with the first conductive member and the connection portion.

7. The electronic device of claim 6 ,
wherein the wireless communication circuit includes a second matching circuit electrically connected with the second conductive member and a grounding area of the PCB.

8. The electronic device of claim 7 , further comprising:
a first switching circuit disposed on the PCB, the first switching circuit configured to selectively electrically connect the first matching circuit to the connection portion.

9. The electronic device of claim 8 , further comprising:
a second switching circuit disposed on the PCB, the second switching circuit configured to selectively electrically connected the second matching circuit to the connection portion.

10. The electronic device of claim 1 , wherein the wireless communication circuit is configured to feed at a first point of a first end of the first conductive member that is adjacent to the slit.

11. The electronic device of claim 10 , wherein the wireless communication circuit is configured to feed at a second point of a second end of the first conductive member, the second end opposite to the first end.

12. The electronic device of claim 1 , wherein the support member is physically coupled to at least one area of the side member, and
wherein the coupling member is coupled to the connection portion such that the PCB is fixed onto the support member.

13. An electronic device comprising:
a side housing including a first conductive member and a second conductive member separated from each other by a slit;
a support member;
a PCB disposed on the support member;
wherein the second conductive member includes a connection part protruding from an area of the second conductive member that is adjacent to the slit, the connection part being physically coupled with the PCB and the support member by the coupling member, and
wherein a wireless communication circuit provided on the PCB is electrically connected and configured to feed power to the first conductive member and to the second conductive member through the connection part, and
wherein the first conductive member at least partially forms an antenna with the second conductive member.

14. The electronic device of claim 13 , wherein a pad including a copper (Cu) pattern is formed on at least a portion of an area of the PCB that makes contact with the connection part, and
wherein the connection part includes an anodizing film area formed on at least a portion of a surface of the connection part such that the connection part is electrically separated from the PCB, and operates as a floating ground.

15. The electronic device of claim 13 ,
wherein the coupling member is a screw tightened to the connection part.

16. The electronic device of claim 13 , further comprising:
a first matching circuit electrically connected with the first conductive member; and
a second matching circuit electrically connected with the second conductive member.

17. The electronic device of claim 16 , further comprising:
