Calculation of antenna radiation center using angular momentum

På svenska

Author

Summary, in English

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 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.
