1. A foldable electronic device comprising a plurality of housings, the electronic device comprising:
a first antenna included in a first side surface of a housing and a portion of a second side surface of the housing;
a second antenna segmented from the first antenna and included in the second side surface;
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 configured to transmit an RF signal to the first antenna and the second antenna or receive an RF signal through the first antenna and the second antenna,
wherein the RF communication circuit is configured to:
perform control such that communication is performed using the first antenna,
determine whether radiation power through the first antenna is equal to or greater than a predetermined value,
in case that the radiation power through the first antenna is greater than or equal to the predetermined value, identify an in-phase quadrature phase (IQ) value of the first antenna,
determine whether the IQ value corresponds to a switching condition of the second antenna, and
in case that the IQ value corresponds to the switching condition of the second antenna, perform switching from the first antenna to the second antenna.
