Abstract: An electronic device is provided. The electronic device includes at least one housing, a plurality of antennas arranged on the at least one housing, at least one radio frequency (RF) circuit, memory, including one or more storage media, storing instructions, and at least one processor communicatively coupled to the at least one RF circuit and the memory, wherein the instructions, when executed by the at least one processor individually or collectively, may cause the electronic device to determine to transmit an RF signal through a first RF path corresponding to a first antenna among the plurality of antennas, identify the state of the at least one housing, identify a maximum transmission power limit corresponding to the first RF path, based on whether an accumulated specific absorption rate (SAR) for the first RF path meets a maximum transmission power limit backoff condition associated with an antenna group, the antenna group being determined according to the state of the at least one housing, and transmit, by the at least one RF circuit, the RF signal based on transmission power set based on the maximum transmission power limit.
