Based on reflection arrangement, two antenna polarization measurement techniques, the absolute polarization measurement method and the polarization‐transfer measurement method are presented with experimental results. In the absolute polarization measurement method or the system calibration, the polarization characteristics of transmitting and receiving dual‐polarization antennas used in the measurement system are determined using the two polarization‐isolated scattering calibrators. In the polarization‐transfer measurement method, the antenna being tested operates in either transmitting mode or receiving mode. Since the transmitting and receiving antennas are located side by side in the measurement system, the phase reference signal between two antennas can be implemented with a short cable.
