1. An electronic device comprising:
a sensor module for sensing whether an external object approaches the electronic device;
a communication module for cellular communication;
a first antenna for the cellular communication;
a short-range wireless communication module for short-range wireless communication;
a second antenna for the short-range wireless communication; and
a processor,
wherein the processor is configured to:
check whether the external object approaches so as to be within a specified range using the sensor module while transmitting a cellular signal with a specified power through the first antenna,
output a specified signal through the second antenna at least based on determination that the external object has approached within the specified range,
obtain a signal caused by the specified signal that is reflected by the external object using the second antenna, and
transmit the cellular signal adjusted to have a lower power than the specified power in case that a phase difference between the specified signal and the reflected signal falls within a specified range, and refrain from adjusting the specified power in case that the phase difference does not fall within the specified range.
