An electronic device according to various embodiments comprises: a UWB communication circuit including at least one antenna for acquiring signals from an external electronic device; a processor operatively connected with the UWB communications circuit; and memory operatively connected with the processor. The memory may store one or more instructions which, when executed, cause the processor to: obtain at least one signal from the at least one antenna; determine a phase-difference-of-arrival of the at least one signal; obtain information related to the state of the electronic device; obtain a calibration value corresponding to the obtained state information of the electronic device from the memory; and determine the angle-of-arrival of the signal on the basis of the phase-difference-of-arrival of the signal and the calibration value.
