Impedance of vertical dipoles above a dissipative ground
Abstract
Self impedance formulas for a small horizontal wire loop and for a short vertical dipole above the ground are derived using the exact image principle. The resulting integrals behave extremely well for low antenna elevations and give good results with the simplest numerical approximations.
