Disclosed is an electronic device that includes a transmission amplifier; an antenna; a circulator disposed between the transmission amplifier and the antenna; a communication module which is connected to the circulator and which is for checking a signal received through the antenna; and a processor. The processor may be set to check the signal through the communication module and adjust the frequency characteristics of the antenna based at least in part on a determination that the signal is a signal reflected from the antenna.

Electronic device for controlling communication circuit on basis of signal received from antenna

Provided are an electronic device for determining failure of a signal path and a component, and a method for operating the electronic device according to various embodiments. The electronic device comprises: at least one connection part for connection to an external device; a first signal path including an amplifier for amplifying a signal transmitted to the outside of the electronic device; a second signal path for obtaining another signal from the outside of the electronic device; an antenna port electrically connected to the first signal path and the second signal path through a filter circuit; and a communication module, wherein the communication module may be configured to transmit a transmission signal through the first signal path to the antenna port, obtain at least a part of the transmission signal through the second signal path, and determine whether the electronic device is defective on the basis of the transmission signal and information associated with at least a part of the transmission signal. Various other embodiments are possible.
