Calculation of antenna radiation center using angular momentum

Fridén, Jonas and Kristensson, Gerhard LU (2013) In IEEE Transactions on Antennas and Propagation 61(12). p.5923-5930
Abstract
An algorithm to compute the radiation center of an antenna, using the Spherical wave expansion (SWE) of the far field or the far field directly, is introduced. The method is based on the angular momentum that is uniquely defined for any antenna far field pattern. The radiation center is defined as the phase reference point where the angular momentum is minimized and corresponds to minimizing the phase variations in the antenna far field pattern. In addition, this approach also allows for determination of the current distribution axis.
