20. A method for operating an electronic device, the electronic device comprising one or more antenna modules, and a DC-to-DC converter disposed outside the one or more antenna modules and configured to supply power to low-dropout regulators included in the one or more antenna modules, respectively, wherein the DC-to-DC converter is configured to establish an electrical path for receiving a feedback signal from each of the low-dropout regulators, the method comprising:
obtaining a feedback signal from at least one antenna module;
comparing a current voltage of a low-dropout regulator included in the obtained feedback signal with a target voltage; and
controlling power supplied to each low-dropout regulator from the DC-to-DC converter, based on a result of the comparing.
