This paper discusses a measurement technique for accurately characterizing low cross polarization level of antennas, and associated sensitivity and errors. The technique involves two-antenna transmission (S21) measurement that includes an AUT and a reference antenna that has low cross polarization level. This
technique needs two far-field transmission data from two different relative roll angles. The crosspolarization sensitivity is determined by SNR of crosspolarization component and cross-polarization of the
reference antenna. The cross-polarization error is related to roll angle uncertainty and receiver noise.
