Near Fields of Thin-Wire Antennas-Computation and Experiment

Abstract

Techniques for the computation of near fields of thinwire antennas have been reported in the past. In this paper, the methods for such computation are reviewed, some recent developments are described, and extensive experimental verification is reported. The computed near fields of resonant dipole are compared with experiment. The near fields of broadside and endfire linear arrays are reported. The broadside near-field patterns narrow, whereas the endfire patterns broaden, as distance from the array center increases. Finally, the relevance of near-field computation to near-field radiation hazards and to near-field measurements is discussed.
