Summary:
Modal analysis on dipole antenna using method of moments and characteristic modes is used to evaluate the amount of the excitation for balanced and unbalanced modes. To separate the current on the antenna into the balanced and unbalanced modes, the current distribution is decomposed into even- and odd-symmetrical distribution with respect to reference plane. As a result, the power ratio of the unbalanced to balanced modes can be numerically computed without setting both balanced and unbalanced feed ports on the analytical model.
