ELECTRONIC DEVICE COMPRISING PLURALITY OF ANTENNAS

An electronic device according to one embodiment comprises: a first mmWave antenna module including a first array antenna; an intermediate frequency (IF) circuit electrically connected to the first mmWave antenna module through a first path; an ultra-wide band (UWB) antenna disposed to be adjacent to the first path; a UWB circuit electrically connected to the UWB antenna; and at least one processor electrically connected to the IF circuit and the UWB circuit, wherein the at least one processor controls the IF circuit to provide a signal of a first frequency band to the first mmWave antenna module, controls the UWB circuit to acquire, through the UWB antenna, a signal of a second frequency band partially overlapping the first frequency band, and may deactivate the UWB antenna or stop communication using the first mmWave antenna module according to whether a specified condition associated with the UWB antenna is satisfied.
