Abstract The movement of antenna s near-field is studied in time domain. The near field distributions are analyzed by using plane wave-spectrum method. A sampling principle is deduced for planar near-field scanning in time domain. Some methods of near-far field transfer are introduced, which can be performed through time or frequency approach. The characteristics of the two approaches are discussed. Extensive numerical results of an H-plane waveguide horn illustrate the analysis.

Key words： Planar near field measurement in time domain Finite-difference time-domain Plane wave-spectrum Near-far fields transfer
