ABSTRACT:
Provided are an apparatus for correcting a phase of a phased array antenna and a method thereof. The apparatus for correcting a phase of a phased array antenna for receiving a radio signal, includes a phased array antenna for receiving radio signals from a reference antenna and combining power of the received radio signals, a power dividing unit for dividing the combined power of the received radio signals, a voltage detecting unit for detecting voltage values of the divided radio signals, and a phase controlling unit for estimating a phase error that makes the detected voltage value maximum and controlling a phase of each radiation element of the phased array antenna using the estimated phase error.
