THE IMAGE THEORY QUASI-STATIC FIELDS OF ANTENNAS ABOVE THE EARTH'S SURFACE.
Abstract
Expressions for the quasi-static range (the measurement distance is much less than a free-space wavelength) field components produced by dipole antennas located above the earth's surface have been derived by employing image theory. Formulas for the field components produced by an elevated, finite-length, horizontal electric antenna are also derived. Image theory is employed because most of the resulting integrals encountered can not be evaluated analytically. The image theory and previously derived analytical (or, in some cases, numerical integration) results are in good agreement throughout the quasi-static range. (Author)
