摘要： An apparatus and a method for phase calibration in an radio frequency (RF) module that constitutes a wireless communication device are provided. The apparatus and method include a test signal is emitted by a forward transmission antenna array of a first antenna array, and the emitted test signal, which is transferred by a member that covers the first and second antenna arrays, is received through a forward reception antenna array of the second antenna array. On the basis of the received test signal, a phase value is calibrated with regard to each of chain combinations formed by the first and second antenna arrays. Forward chain combinations that constitute the chain combination may be determined by a combination of forward transmission chains, which correspond to respective transmission antennas that constitute the forward transmission antenna array, and forward reception chains, which correspond to respective reception antennas that constitute the forward reception antenna array.
