Receiving and scattering characteristics of an imaged monopole beneath a lossy sheet

An analytical treatment of the radiation, scattering, and receiving properties of an imaged monopole in trilayered media with a perfectly conducting ground plane, a dielectric substrate, an electrically or magnetically lossy sheet as superstrate, and a homogeneous cover region is carried out. It is shown that while the power received by the monopole antenna is reduced by the presence of the lossy sheet, the scattered field is more greatly reduced, in agreement with observed behavior. Comparison with experimental and previously published numerical results validates the analysis.<
