An electronic device, according to various embodiments, comprises: a communication processor; an intermediate frequency integrated circuit (IFIC) connected to the communication processor and converting a baseband signal received from the communication processor into an intermediate frequency (IF) signal; a radio frequency integrated circuit (RFIC) for converting the received IF signal into a first radio frequency (RF) signal; an ultra-wideband (UWB) integrated circuit (IC) for generating a UWB signal corresponding to a first frequency; at least one UWB antenna for transmitting/receiving the UWB signal corresponding to the first frequency; and at least one first switch connected between the UWB IC and the UWB antenna, wherein the at least one first switch may be controlled so that the UWB signal corresponding to the first frequency, generated in the UWB IC, is transmitted to the RFIC in a state where a communication operation of the RFIC with respect to a signal transmitted/received to/from the communication processor is disabled.
