1. An electronic device, comprising:
a first antenna and a second antenna;
a battery;
a wireless communication module having a coupler; and
a processor electrically connected with the first and second antennas, the battery, and the wireless communication module, wherein the processor is configured to:
measure a magnitude of a component corresponding to a designated frequency band of a coupling signal fed back from the coupler based on a first signal transmitted or received through the first antenna,
compare the measured magnitude with a designated threshold, and
control at least some elements of the electronic device to allow the measured magnitude to be reduced to the designated threshold or less if the measured magnitude exceeds the designated threshold,
wherein the processor is configured to perform at least one of increasing a current supplied to a power amplifier provided in the wireless communication module, reducing power for transmitting the first signal through the first antenna, or switching into a functional element where no resonance occurs with the second antenna to allow the measured magnitude to be reduced to the designated threshold or less, and
wherein the processor is configured to select the functional element where no resonance occurs with the second antenna in an antenna switching module including a plurality of functional elements.
