Near-field antenna measurement method and measurement system using the same

A near-field antenna measurement system comprising:

• a positioner;
• an electric field measurement device arranged on said positioner, and a position of said electric field measurement device corresponds to a position of a measurement block of an antenna under test;
• and
• a processing device connected with said positioner and said electric field measurement device, moving said electric field measurement device to a plurality of initial measurement points at a boundary of said measurement block through said positioner, using said electric field measurement device to measure initial electric field values of an antenna signal emitted by said antenna under test at said initial measurement points, choosing a plurality of initial interpolation points different from said initial measurement points on said measurement block, and a distance between each said initial interpolation point and either said initial interpolation point or said initial measurement point neighboring thereto is less than a half of a wavelength of said antenna signal, and said processing device performs interpolation on said initial electric field values to obtain initial electric field interpolation values respectively corresponding to said initial interpolation points, and said processing device processes said initial electric field values and said initial electric field interpolation values to obtain electric filed convergence values of said antenna signal at said initial measurement points and said initial interpolation points.
