Modern spherical near-field to far-field transformation algorithms, in contrast to Fourier based ones, offer arbitrary sampling grids without inherent oversampling. This raises the question how the measurement samples should be distributed on the sphere. In this paper different sampling grids for spherical near-field antenna measurements are presented and evalu- ated. It is shown that the spherical transformation problem is in general well-conditioned and can be solved accurately. Measurement results emphasize the possible measurement time reduction due to the reduction of oversampling. However, positioning hardware has to be included in the analysis, because complex measurement trajectories might increase the measurement time.
