Abstract
An antenna system includes a multi-port antenna with an active feeding network coupled thereto. The active feeding network applies complex weights to signals received from and transmitted to each port of the multi-port antenna. The complex weights are applied according to eigenvectors corresponding to a Hermitian matrix representation of the multi-port antenna. The Hermitian matrix may be base on such multi-port antenna parameters such as power dissipation, power radiation, real-power flow, volumetric storage of electromagnetic energy, and/or volumetric dissipation of electromagnetic energy. The multi-port antenna yields orthogonal electromagnetic fields in volumes or surfaces of interest in response to the active feeding network excitation.
