Abstract: This paper proposes a novel method to measure the wide-angle scanning phased array antenna based on coordinate transformation, in order to solve the problem of planar near-field antenna measurement in the wide-angle scanning phased array antenna. On the basis of coordinate transformation theory analysis, computer numerical simulation is completed and the physical antenna is fabricated and measured. The results illustrate that the measurement method presented in this paper has a good accuracy to measure the wide-angle scanning phased array antenna.

Key words: planar near-field antenna measurement, phased array antenna, coordinate transformation, probe correction
