1. An electronic device comprising:
a housing;
a wireless communication circuit positioned inside the housing and configured to transmit or 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 operatively connected to the wireless communication circuit; and
a memory operatively connected to the at least one processor,
wherein the memory is configured to 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; and
instructions that, when executed, cause the at least one 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 so as to identify whether the measurement value is included within at least one designated range;
identify a second antenna mode corresponding to the acquired measurement value among the antenna modes included in the second set, in case that it is identified that the measurement value is included within the at least one designated range; and
cause the wireless communication circuit to transmit the signal in the second antenna mode.
