1. An electronic device comprising:
a display disposed on a front surface of the electronic device;
an ultra-wide band (UWB) antenna including directional antennas disposed on a rear surface opposite to the front surface and forming a radiation pattern in a direction to which the rear surface faces, and at least one omnidirectional antenna forming an omnidirectional radiation pattern compared to the directional antennas;
a processor;
a communication circuit configured to convert a message to be transmitted to an external electronic device received from the processor into a radio frequency (RF) signal of a frequency band designated to be used for UWB communication, and output the RF signal to the UWB antenna, and configured to convert an RF signal received from the external electronic device through the UWB antenna into a message, and output the message to the processor; and
a memory operatively connected to the processor,
wherein the memory stores instructions that cause, when executed, the processor to:
calculate a first distance value, based on a first time at which a first message is received from the external electronic device through the UWB antenna, a second time at which a second message is transmitted to the external electronic device through the UWB antenna, a third time at which a third message is received from the external electronic device through at least one of the directional antennas of the UWB antenna, and time information received from the external electronic device through the UWB antenna,
calculate a second distance value, based on the first time, the second time, a fourth time at which the third message is received from the external electronic device through the at least one omnidirectional antenna of the UWB antenna, and the time information, and
based on a distance difference between the first distance value and the second distance value, determine whether the external electronic device exists within a field of view (FoV) indicating a specified angular range with respect to the direction to which the rear surface faces.
