The proposed method demonstrates phase retrieval in antenna measurements, indicating advancements in differential evolution algorithms.
This paper proposes a near‐field measurement scheme for phase retrieval based on the differential evolution algorithm (DEA), which can obtain the far field radiation characteristics only by obtaining the amplitude information of antenna. Using differential evolution algorithm to find the appropriate initial iterative phase, and then using the Iterative Fourier Transform Algorithm to fine restore the phase of the scanning point position, which can effectively solve some difficult problems of near‐field phase acquisition for antennas. The actual measurement has proved that the proposed method can effectively solve the antenna near‐field phase retrieval problem by testing the array antenna, and realize the phase‐free near‐field measurement of the millimeter‐wave antenna.
