Input impedance of a dipole antenna above a conducting half space

Input impedance of a dipole antenna above a conducting half space

The derivation of an expression for the change in free space input impedance of a finite horizontal dipole, due to the proximity of a conducting half space, is outlined. The impedance change is expressed in a conveniently computable form in terms of the Fourier transform of the antenna current distr...

Zusammenfassung:The derivation of an expression for the change in free space input impedance of a finite horizontal dipole, due to the proximity of a conducting half space, is outlined. The impedance change is expressed in a conveniently computable form in terms of the Fourier transform of the antenna current distribution. Using available transforms some typical results are shown over a 50:1 frequency range.
