Method of recognizing immersion and electronic device for performing the same

An electronic device comprising:

• a first antenna and a second antenna which transmit and receive a radio frequency (RF) signal;
• an RF circuit which processes the RF signal;
• and
• a control circuit which controls the RF circuit,
• wherein the control circuit determines whether a water immersion of the electronic device occurs based on an occurrence of interference between a first RF signal transmitted and received through the first antenna and a second RF signal transmitted and received through the second antenna, and performs a set operation once it is determined that the water immersion of the electronic device occurs.

A method of recognizing a water immersion of an electronic device, the method comprising:

• receiving a feedback signal corresponding to a radio frequency (RF) signal transmitted and received through an antenna of the electronic device,
• determining an impedance of the antenna based on the received feedback signal,
• determining whether the water immersion of the electronic device occurs based on the determined impedance;
• and
• performing a set operation by the electronic device once it is determined that the water immersion of the electronic device occurs.
