摘要

The paper deals with a simple analytical approach to determine the antenna parameters pertaining to near field zone, such as imaginary part of Poynting vector or the reactive power stored in the thin wire near field. The reactive power is obtained from the Poynting theorem in the complex phasor form. Simple closed form expressions for the electric and magnetic fields in the near field zone are used. An approximate sinusoidal form of the current distribution along the dipole is assumed.
