Absorption efficiency and physical bounds on antennas
(2010) In Technical Report LUTEDX/(TEAT-7200)/1-20/(2010)- 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.
