Aperture Extrapolation in Planar Near-field Measurement

摘要

The implementation of the planar-near-field technique necessitates the measurement on a truncated-plane surface. In some cases, the probe track and carriage of the near field equipment may not be able to provide sufficient range. To solve this problem, in this paper, the concept of the aperture extrapolation is introduced and verified. This extrapolation is carried out through the spectral estimation. The results show the good prospects in the application of the near-field measurement.
