Abstract: Disclosed is an electronic device that may sense the proximity of a user by using a director of an antenna module as an electrode of a grip sensor without a separate sensor for detecting the user's proximity, thereby enabling efficient use of the internal space of the electronic device without having to secure a space for mounting a separate sensor. The electronic device may also reduce the power of a transmission signal by a preset back-off value in response to sensing the user's proximity, thereby minimize an adverse effect of electromagnetic waves on the human body caused by signal transmission.
