Abstract
An electronic device may include: a memory storing a plurality of antenna configurations, at least one communication processor configured to support at least one network communication, at least one antenna configured to transmit at least one communication signal corresponding to the at least one network communication, and at least one antenna-tuning circuit configured to adjust a resonance characteristic of the at least one antenna, wherein the at least one communication processor is configured to: identify a cumulative specific absorption rate (SAR) value associated with emission of the at least one communication signal based on an antenna configuration of the at least one antenna-tuning circuit among the plurality of antenna configurations; and adjust a transmission strength of a communication signal corresponding to at least one of the at least one network communication based on the cumulative SAR value satisfying a designated condition.
