  "claims": [
    "1. An electronic device which photographs an image, comprising: a housing where an opening is formed; a printed circuit board (PCB) disposed in the housing; an insulating member coupled to the PCB; a first radiator formed on the insulating member; a camera electrically connected with the PCB, and configured to capture the image through the opening; a decoration surrounding the opening; a second radiator including at least a portion of the decoration; and a communication circuit configured to feed a power to the first radiator, wherein the communication circuit indirectly feeds the power to the second radiator through the first radiator and transmits/receives a signal in a specified frequency band through an electrical path formed by the first radiator and the second radiator. 2. The electronic device of claim 1, wherein the first radiator and the second radiator are electrically connected by a coupling. 3. The electronic device of claim 1, further comprising: a flexible printed circuit board (FPCB) electrically connected with a ground layer disposed in the PCB; and a third radiator including at least a portion of the FPCB. 4. The electronic device of claim 3, wherein the communication circuit indirectly feeds the power to the third radiator through the first radiator and indirectly feeds the power to the second radiator through the third radiator. 5. The electronic device of claim 4, wherein the communication circuit transmits/receives the signal in the specified frequency band through an electrical path formed by the first radiator, the third radiator, and the second radiator. 6. The electronic device of claim 3, wherein the third radiator and the second radiator are electrically connected by a coupling. 7. The electronic device of claim 1, wherein the decoration includes a conductive member electrically connected to the second radiator. 8. The electronic device of claim 1, wherein at least a portion of the second radiator is segmented. 9. The electronic device of claim 1, further comprising: an additional decoration disposed on a side of the PCB, which faces away from the decoration, and electrically connected with the decoration. 10. The electronic device of claim 9, wherein the communication circuit transmits/receives a signal in a frequency band different from the specified frequency band through an electrical path formed by the first radiator, the second radiator, and the additional decoration. 11. The electronic device of claim 9, further comprising: an additional insulating member disposed on a side of the PCB, which faces away from the insulating member, wherein the communication circuit transmits/receives a signal in a frequency band different from the specified frequency band through an electrical path formed by a third radiator formed on the additional insulating member and a fourth radiator including at least a portion of the additional decoration. 12. The electronic device of claim 1, wherein the communication circuit changes a frequency for transmitting/receiving the signal based on a diameter of the decoration. 13. An electronic device comprising: a housing where an opening is formed; a printed circuit board (PCB) disposed in the housing; an insulating member coupled to the PCB; a first radiator formed on the insulating member; a camera electrically connected with the PCB and exposed through the opening; a decoration surrounding the opening; a flexible printed circuit board (FPCB) including one end located between the first radiator and the decoration and an opposite end electrically connected with a ground layer in the PCB; a second radiator including at least a portion of the FPCB; a third radiator including at least a portion of the decoration; and a communication circuit configured to feed a power to the first radiator, wherein the communication circuit indirectly feeds a power to the second radiator and the third radiator through the first radiator and transmits/receives a signal in a specified frequency band through an electrical path formed by the first radiator, the second radiator, and the third radiator. 14. The electronic device of claim 13, wherein the communication circuit changes a frequency for transmitting/receiving the signal based on a length of the second radiator. 15. The electronic device of claim 13, further comprising: a switch connecting one point on the second radiator and the ground layer."

  "description_excerpt": "Embodiments of the disclosure relates to a technology for improving performance of an antenna.\n\nAs mobile communication technologies develop, there is being widely supplied an electronic device such as a smartphone or a wearable device. The electronic device may communicate with another electronic device. For example, the electronic device may transmit/receive a message, a photo, a video, or the like to/from the another electronic device. To this end, an antenna capable of communicating with the another electronic device may be mounted on the electronic device.\n\nThe electronic device may include other metal components as well as the antenna. For example, the electronic device may include a metal housing for protecting the electronic device from external impact.\n\nHowever, the above metal components may reduce performance of an antenna. For example, a signal radiated through the antenna is induced at the metal components, and a transmission efficiency of the antenna may decrease. For example, a signal received from another electronic device, which can be induced at the metal components, may degrade a reception efficiency of the antenna.\n\nVarious embodiments of the disclosure provide an electronic device for solving the above-described problems brought up in this specification.",
