Physical limitations of antennas in a lossy medium

Research output: Book/ReportReportResearch


The dissipated power and the directivity of antennas in a homogeneous, lossy
medium are systematically analyzed in this paper. The antennas are ideal
and located inside a lossless sphere. In the lossy space outside the sphere, the
electromagnetic fields are expanded in a complete set of vector wave functions.
The optimal values of the radiation efficiency, the directivity, as well as the
power gain are derived.
