AN EXPERIMENTAL INVESTIGATION ON THE BEHAVIOR OF THE DIPOLE ANTENNA NEAR THE INTERFACE BETWEEN THE CONDUCTING MEDIUM AND FREE SPACE

摘要

An experimental study was made of the driving-point admittance and The relative amplitude and phase distributions of the current for a dipole antenna near and parallel to the interface between the conducting medium and free space. (The antenna was always located in the conducting medium, unless otherwise specified.) The depth d of the antenna from the interface was varied from d/X = 4. 4 to 0. The loss tangent of the conductingnmedium was varied from 0. 036 to 8. 8 , a range which includes a variety of media such as poor insulators, the ionosphere, plasmas, dry earth, wet earth, lake water, and sea water. The antenna height h in radians was varied from ph = 0.1 through 2V
