Abstract

The input resistance and the effective height are computed, with reference to several antennas in conductive environment in the limiting static case. For a gap type excitation, it is found that the above parameters are logarithmic functions of the gap thickness. Experiments performed on models confirming theoretical deductions are also reported. The possibility of extending static results to the dynamic case is also discussed, as well as the performance of the antennas in the more realistic semi-infinite (and possibly layered) conducting environment.
