Electronic device for determining angle-of-arrival of signal, and method for operating electronic device

A method of operating a foldable electronic device, the method comprising:

• obtaining at least two signals respectively received at least two antennas from an external electronic device;
• determining a phase-difference-of-arrival of the at least two signals based on a phase of each of the at least two signals;
• identifying information related to a folding angle of the foldable electronic device;
• identifying, from a memory, calibration information corresponding to the identified information related to the folding angle, the calibration information being for determining an angle-of-arrival of the at least two signals;
• and
• determining the angle-of-arrival of the at least two signals, based on the phase-difference-of-arrival of the at least two signals and the calibration information.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of a foldable electronic device, cause the foldable electronic device to perform operations, the operations comprising:

• obtaining at least two signals respectively received at least two antennas from an external electronic device;
• determining a phase-difference-of-arrival of the at least two signals based on a phase of each of the at least two signals;
• identifying information related to a folding angle of the foldable electronic device;
• identifying, from memory, calibration information corresponding to the identified information of the foldable electronic device, the calibration information being for determining an angle-of-arrival of the at least two signals;
• and
• determining the angle-of-arrival of the at least two signals, based on the phase-difference-of-arrival of the at least two signals and the calibration information.
