Abstract :
The changes in input impedance for a simple antenna or transmission line located over a soil containing a conducting object are examined near antiresonance. The near-field coupling of the underground object to the antenna or transmission line is investigated using the complex Poynting vector in order to identify the contribution of traveling and/or standing waves.
