The field associated with energy stored in the antenna is which?

Explanation:
The energy that stays temporarily near the antenna is stored in the inductive (magnetic) part of the near field. When current changes in the conductor, it builds up magnetic energy around it; this is reactive energy that oscillates with the signal and is not radiated away. The other concepts describe energy that travels away (radiation and propagation) or how waves interact with boundaries (reflection), which do not represent the stored energy in the near field. So the inductive field best captures the energy stored around the antenna.
