Absorption Efficiency and Physical Bounds on Antennas

Gustafsson, Mats LU orcid ; Cismasu, Marius LU and Nordebo, Sven LU (2010) In International Journal of Antennas and Propagation 2010.
Abstract
Abstract—The all spectrum absorption efficiency appears in

the physical bounds on antennas expressed in the polarizability

dyadics. Here, it is shown that this generalized absorption

efficiency is close to 1/2 for small idealized dipole antennas and

for antennas with a dominant resonance in their absorption. Also,

the usefulness of this parameter is analyzed for estimation of

antenna performance. The results are illustrated with numerical

data for several antennas.
