Physical limitations on D/Q for antennas

Gustafsson, Mats LU ; Sohl, Christian LU and Kristensson, Gerhard LU (2007) International Symposium on Electromagnetic Theory, 2007 p.1-3
Abstract
In this paper, physical limitations on the directivity D and Q-factor Q are derived for antennas of arbitrary shape. The quotient D/Q is shown to be bounded from above by the antenna volume and certain shape coefficients in terms of the eigenvalues of the high-contrast polarizability dyadic. The theory is exemplified by numerical results for the half-wave antenna with astonishing agreement.
