Abstract :
When utilizing an antenna over ground as a near-field probe for detecting underground conducting objects, maximizing the variation in the antenna input impedance due to the buried object is the primary concern. Using the example of a horizontal dipole and a buried cylinder, significant variation in the dipole input impedance is obtained by carefully positioning the antiresonant dipole to excite the dominant cylinder resonance.
