What characterizes the electric and magnetic fields in the antenna's near field region?

Answer

They are closely coupled and primarily reactive, storing and returning energy to the antenna structure.

In the immediate vicinity of the antenna, known as the near field, the fields are closely coupled and primarily reactive, meaning they store and return energy to the antenna structure on each cycle without significant radiation.
