1. An electronic device comprising:
a hinge module;
a first housing at least partially coupled to a first side of the hinge module and comprising a first antenna;
a second housing at least partially coupled to a second side of the hinge module, the second housing configured to be foldable and unfoldable with the first housing by using the hinge module, and comprising a second antenna;
a sensor circuit configured to detect at least one of an unfolding state or a folding state of the first housing and the second housing;
a memory;
a processor operatively connected to the first antenna, the second antenna, the sensor circuit, and the memory;
a first signal line configured to connect the processor and the first antenna;
a tuner circuit;
a second signal line configured to connect the processor and the second antenna;
a third signal line; and
a divider,
wherein the processor is configured to:
transmit a signal to the second antenna through the second signal line,
based on the detection of the folding state using the sensor circuit, receive the signal transmitted to the second antenna as a feedback signal through the third signal line,
detect a phase of the feedback signal,
determine a time constant of the tuner circuit disposed on the first signal line, based on the detected phase of the feedback signal,
adjust a phase of the first antenna based on the determined time constant of the tuner circuit, and
in case that the tuner circuit comprises a phase shifter disposed between the processor and the first antenna and the second antenna, wherein the processor is configured to change, based on a control value of the phase shifter stored in the memory, a phase of a first signal and transmitted to the first antenna and a phase of a second signal transmitted to the second antenna distributed by the divider.
