Abstract :
This paper proposes an array antenna calibration method for array antenna systems. The proposed method calibrates the amplitude and the phase of RF systems using internal coupler and switches without aids of external calibration systems. Computer simulation demonstrates that the proposed method corrects beamforming angles.
