Abstract: A planar near-field test method based on the frequency shift characteristics of Fourier transform is proposed to meet the requirements of fast and phase-free test of field antenna. This method adopts multi probe technology and uses the phase shift of each channel to achieve the movement of antenna angle domain and realize the acquisition of arbitrary pointing angle signal. This paper performs the planar near-field scanning measurement on a standard horn antenna. Experiments show that this method has the same effect as the traditional near-field test method, and can effectively test the antenna pattern. This method has the characteristics of fast test and convenient use. It is especially suitable for large-scale production test and field test of antenna.
