A study of evanescent waves and the effect on antenna near field is presented. By computer simulation using a simple well-known dipole antenna, the effect of evanescent waves on the near field distribution is investigated by the plane wave spectrum method. Although the evanescent waves make no contribution to the far-field, they do make a contribution to the aperture distribution. The evanescent waves can be readily examined in the spectral domain.
