Theory of Planar Near-Field Measurement
Abstract
The theory of planar near-field measurement is discussed for two different approaches: The scattering-matrix formulation approach and the reciprocity theorem approach. The interaction of test antenna and probe antenna is calculated, in which is taken account of the presence of the probe used to sample the field distributions since the probe is not assumed to be ideal (elementary magnetic or electric dipole), it is said that probe correction is applied. It is shown that both approaches lead to equal results. The derivation of far-field antenna characteristics from near-field data is then discussed and near-future research items are shortly mentioned.
