A Rapid Antenna Phase Center Correction Approach for Spherical Near-Field Measurements

This paper presents a rapid phase center calculation method for spherical near-field antenna measurements. Compared with traditional methods, the proposed approach eliminates the need for complex model assumptions or additional equipment, introducing no extra parameters. This significantly reduces computational complexity, providing a simpler and more robust solution. Moreover, the method demonstrates broad applicability, supporting various types of antennas and enabling fast and accurate phase center corrections. Its versatility and efficiency make it particularly well-suited for practical measurement scenarios where high precision and efficiency are critical, thereby effectively improving the accuracy and reliability of measurement results.
