Abstract
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The method is for phase correction of an antenna in a large-capacity antenna system, the method includes grouping large-capacity antennas into a predetermined number of groups; setting a path such that ports of the grouped antennas have a feedback path; outputting a test signal to be outputted to each antenna port of each group by adding a code or sequence having orthogonality; separating signals for each antenna port in the group by using the code or sequence having orthogonality in a signal received through the feedback path; and calculating a calibration value by detecting a phase change of the separated signal.
