Abstract: An electronic device is provided. The electronic device includes a first antenna, a second antenna segmented from the first antenna, a switch selectively coupled to the first antenna and the second antenna, a front end module connected to the switch, and a radio frequency (RF) communication circuit, wherein the RF communication circuit controls to communicate using the first antenna, determines whether radiation power through the first antenna is equal to or greater than a predetermined value, and if the radiation power through the first antenna is greater than or equal to the predetermined value, checks the in-phase quadrature phase (IQ) value of the first antenna, determines whether the IQ value corresponds to a switching condition of the second antenna, and if the IQ value corresponds to the switching condition of the second antenna, may switch the first antenna to the second antenna.
