Abstract: According to various embodiments, an electronic device may include multiple antennas, at least one antenna tuning circuit connected to at least one antenna among the multiple antennas, and at least one communication processor, wherein the at least one communication processor receives, through a first antenna among the multiple antennas, a signal transmitted from a base station based on multiple-input and multiple-output (MIMO), receives, through a second antenna among the multiple antennas, a signal transmitted from the base station based on the MIMO, and when a strength of a first signal received through the first antenna or a strength of a second signal received through the second antenna is equal to or greater than a first threshold value, determines whether an imbalance condition of the first signal and the second signal is satisfied, and adjusts, when the imbalance condition is satisfied, a setting value of the at least one antenna tuning circuit so as to reduce a difference between the strength of the f

Abstract: An electronic device may include at least one communication processor and at least one short-range communication module. A first RF signal for cellular communication can be controlled to be provided to a first antenna. The at least one short-range communication module can be configured to control that a second RF signal for non-cellular communication is provided to a second antenna included in a first antenna group including the first antenna. The at least one communication processor can be configured such that it is determined, on the basis of a confirmation that a SAR accumulation value corresponding to the first antenna group satisfies a designated condition, that a third RF signal for non-cellular communication is provided to a third antenna included in a second antenna group differing from the first antenna group.
