Abstract

An electronic device includes a camera cover, a wireless communication circuit, a first frame, a second frame and a third frame, extends from a second surface along a part not included in a first surface and the second surface among the periphery of the camera cover, and is connected to the camera cover. The second frame is positioned away from the first frame to form a part of the second surface, and extends from the second surface to form a part of a third surface. The third frame has a gap from the first frame in a specific direction in a first area and is connected to the first frame in a second area. The wireless communication circuit can receive a signal of a specific frequency band by feeding power to a slot structure comprising the gap between the first frame and the third frame.

First claim

The invention claimed is:

1. An electronic device comprising:
a frame structure including a first frame and a second frame, wherein the first frame forms a portion of a first side face of the electronic device and a portion of a second side face extending from the first side face, and wherein the second frame forms a portion of the second side face and is spaced apart from the first frame;
a camera cover integrally formed with the first frame or coupled with the first frame to form a portion of the first side face and a portion of the second side face, wherein the camera cover comprises a first corner at which the first side face and the second side face are connected;
a conductive plate; and
a wireless communication circuit,
wherein the first frame includes a portion extended from the second side face along a periphery portion of the camera cover that is not included in the first side face and the second side face,
wherein the conductive plate includes a first area spaced apart from the first frame by a gap and a second area coupled with the first frame, and
wherein the wireless communication circuit is configured to:
feed power to a point of the portion of the first frame, and
receive a signal of a specific frequency band based on an electrical path formed in the first frame and the conductive plate along a first slot structure comprising the gap.

2. The electronic device of claim 1 , wherein a first portion of the first frame and a second portion of the conductive plate form a portion of the first slot structure,
and
wherein the wireless communication circuit is configured to receive a first signal based on an electrical path formed in the first portion and the second portion.

3. The electronic device of claim 2 , wherein the wireless communication circuit is configured to feed power to a point of the conductive plate to receive a signal of the specific frequency band.

4. The electronic device of claim 1 , wherein a non-conductive material is disposed between the first frame and the conductive plate,
wherein a second slot structure is formed to extend from the non-conductive material and disposed between the first frame and the conductive plate,
wherein a first portion of the first frame and a second portion of the conductive plate form the second slot structure, and
wherein the wireless communication circuit is configured to receive a first signal based on an electrical path formed in the first portion and the second portion.

5. The electronic device of claim 1 , further comprising:
a printed circuit board comprising a ground area,
wherein the wireless communication circuit is disposed on the printed circuit board,
and
wherein the first frame comprises a protrusion including the point and disposed adjacent to the printed circuit board.

6. The electronic device of claim 5 , wherein the wireless communication circuit is configured to feed power to the protrusion of the first frame.

7. The electronic device of claim 6 , wherein a conductive connection member electrically connects the protrusion of the first frame and the printed circuit board.

8. The electronic device of claim 6 , wherein the wireless communication circuit is configured to feed power to the protrusion of the first frame via an electromagnetic coupling.

9. The electronic device of claim 1 , wherein the specific frequency band comprises 1500 to 2500 MHz.

10. The electronic device of claim 1 , wherein the first frame comprises a coupling portion connected with the second area of the conductive plate, and
wherein the coupling portion of the first frame further comprises an additional slot structure.

11. The electronic device of claim 1 , further comprising:
a first non-conductive member disposed between the first frame and the second frame; and
a second non-conductive member disposed between the first frame and the conductive plate.

12. The electronic device of claim 1 , further comprising:
a conductive pattern for feeding the power to the point of the portion of the first frame.

13. The electronic device of claim 1 , wherein the frame structure further includes a third frame spaced apart from the second frame and parallel with the first frame, and
wherein the conductive plate is included in the third frame.

14. The electronic device of claim 1 , wherein the second frame is spaced apart from a third area of the conductive plate by a gap, and
wherein the second frame is connected with a fourth area of the conductive plate via a conductive connection member.

15. The electronic device of claim 1 , wherein the first frame further comprises a first protrusion and a second protrusion for feeding.
