  • Patent number: 11251882
    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). The present disclosure provides a device and a method for calibrating a phased array antenna. A method for calibrating a phased array antenna according to various embodiments of the disclosure comprises the processes of: controlling a first radio frequency (RF) chain so as to transmit a first signal at a first phase, thereby determining the phase difference between the first phase and a reference phase; controlling the first RF chain so as to transmit a second signal at a second phase, thereby determining the phase condition of the phase difference; and calibrating the first RF chain on the basis of the phase difference and the phase condition. The reference phase may be the phase of a reference signal transmitted from a reference RF chain.
