Mm-wave is expected to be one of the important technologies for 5G wireless communication system, and it is necessary for us to study its radio propagation characteristics, which is helpful for channel modeling. Since we have to carry out a large number of channel measurement campaigns, obtaining the antenna pattern of mm-wave horn antenna on different rotating platforms in different scenarios is an important but difficult work. In this paper, we propose an axis calibration method that just needs to measure the antenna pattern once in the anechoic chamber and do a simple measurement in the practical application scenario, then the exact antenna pattern on different rotating platforms can be calculated out based on previous measured antenna pattern in the anechoic chamber, which can save much measuring time. What is more, we also use simulation and practical channel measurement experiment to validate the accuracy of the proposed method, and the relationship between SNR and axis error is analyzed.
