Abstract: According to various embodiments, an electronic device may comprise: a housing; a wireless communication circuit positioned inside the housing so as to transmit/receive at least one radio frequency (RF) signal; multiple antennas positioned inside the housing or configured as parts of the housing and electrically connected to the wireless communication circuit; at least one processor operably connected to the wireless communication circuit; and a memory operably connected to the at least one processor. The memory may store a lookup table comprising a first set of antenna modes regarding at least some of the multiple antennas and a second set of antenna modes regarding at least some of the multiple antennas. In addition, the memory may store instructions that, when executed, cause the processor to: cause the wireless communication circuit to transmit a signal in a first antenna mode included in the first set; cause the wireless communication circuit to receive a reflective wave of the transmitted signal; acquire a measurement value of the received reflective wave; confirm whether the measurement value is included within at least one designated range; confirm a second antenna mode corresponding to the acquired measurement value, among the antenna modes included in the second set, if it is confirmed that the measurement value is included in at least one designated value; and cause the wireless communication circuit to transmit the signal in the second antenna mode. Other various embodiments are possible.
