An antenna structure includes a first antenna, a second antenna, at least one processor, a power distribution circuit configured to equally supply power supplied from the processor(s) to the first antenna and the second antenna, and a coupler disposed between the processor(s) and the power distribution circuit, wherein the processor(s) may 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 a matching parameter based on parameters corresponding to a case 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.

Provided is an iron device. The iron device includes a base provided with a heat generator; a press plate arranged to pivot between a first position at which the press plate covers the base and a second position at which the press plate uncovers the base; a steam nozzle arranged to, with the press plate being in the first position, supply steam to a space between the base and the press plate; and a press driver configured to, with the press plate being in the first position, mechanically move the press plate in a first direction toward the base and second direction away from the base.
