Numerical Modeling of Antenna Near Field

Abstract

This work provides numerical modeling for the near field of a wire antenna. The conventional near field definition is provided along with an explanation for the maximum power density in the near field. Numerical results are provided for the electric and magnetic fields in the near field region. The results obtained from the model are shown to compare very well with data available in the literature for the thin wire case. The variation of the wave impedance and power density are also studied. A listing of the code developed in MATLAB is included in an appendix.
