Traditionally, the superluminal behaviors of evanescent waves have been studied by means of tunneling time theory. Seeing that evanescent waves are identical with near fields, to present a heuristic and straightforward explanation for the superluminal behaviors of evanescent waves, in this paper we study the superluminal behaviors of the near fields of an electric dipole antenna, and obtain the results in agreement with the phase time model of tunneling time theory.
