Calculation of antenna radiation center using angular momentum

Fridén, Jonas and Kristensson, Gerhard LU (2013) 7th European Conference on Antennas and Propagation (EuCAP), 2013 In 7th European Conference on Antennas and Propagation (EuCAP), 2013 p.1531-1535
Abstract
An algorithm to compute the Radiation center of an antenna based on the Spherical wave expansion is introduced. The method is based on the angular momentum vector that is uniquely defined for any antenna far field pattern. The radiation center is defined as the unique point where the magnitude of the angular momentum is minimized with respect to translations of the far field. This corresponds to minimizing the phase variations in the antenna far field pattern. In addition the Current distribution axis can be determined, corresponding to minimization of the vertical component of angular momentum.
