Electronic device including antenna

An electronic device comprising:

• a first conductive portion at least partially exposed to outside of the electronic device;
• a second conductive portion at least partially exposed to outside of the electronic device;
• a coil;
• a near-field communication (NFC) circuitry;
• and
• a transmission line connected with the first conductive portion, the second conductive portion, the coil, and the NFC circuitry, comprising:
• a first signal path connected with a first terminal of the NFC circuitry and a first area of the first conductive portion,
• a second signal path connected with a second terminal of the NFC circuitry and a first ending portion of the coil,
• a third signal path connected with a first area of the second conductive portion and a second ending portion of the coil, and
• a fourth signal path connected with a second area of the first conductive portion and a second area of the second conductive portion, and
• wherein a signal path, which is selected between the first signal path, the second signal path, the third signal path, and the fourth signal path, includes a first ground path and a second ground path that are connected to a ground area of the electronic device.
