1. An antenna structure comprising:
a first antenna;
a second antenna;
at least one processor;
a power distribution circuit configured to equally supply power supplied from the at least one processor to the first antenna and the second antenna; and
a coupler disposed between the at least one processor and the power distribution circuit,
wherein the at least one processor is configured to:
obtain a first parameter for a first signal received by the first antenna and a second parameter for a second signal received by the second antenna;
detect a phase difference between the first signal and the second signal;
obtain matching parameters, based on parameters corresponding to cases in which the phase difference satisfies a specified condition among the first parameter and the second parameter; and
obtain a third parameter for allowing a reflection coefficient of a signal flowing from the power distribution circuit to the coupler to exist within a specified range among the matching parameters.
