Abstract
A computer-implemented method for determining the phase center of an antenna under test comprises the following steps: acquiring a transmitted near-field or far-field signal of the antenna under test, by rotational movement of a measuring antenna relative to the antenna under test, the rotation covering at least the angle between the z axis and the x axis of the antenna, the rotational movement covering a spherical measurement region, the acquisition being performed at different angles phi to the z axis and while rotating, relative to the measuring antenna, the antenna under test around its z axis, obtaining far-field phase data by applying a field transformation on the near-filed or far-filed signal obtained, determining the main beam peak location within the measurement region, and transforming the coordinate center of the far-field data based on the main beam peak location in order to determine the phase center.
