The acquisition of three-dimensional radiation pattern is very important for characterizing antenna. Spherical antenna measurement is a practical approach to measure antenna pattern; however, due to the limitation of measurement range and measurement time, the measured samples may either be incomplete on scanning sphere, or be inadequate in sampling interval. Extrapolation and interpolation are needed to reconstruct the samples. Spherical wave expansion provides a good approach for pattern reconstruction, and its band-limited property makes it possible to be analysed by the sampling theorem. This research identifies the limitation of pattern reconstruction by conventional algorithm, and proposes a novel approach to virtually center the antenna position by the phase shift of measured samples. Numerical investigations are conducted to validate the proposed algorithm for both complete and incomplete data.
