Selective excitation of characteristic modes on an electrically large antenna for MIMO applications

authored by: Nikolai Peitzmeier, Dirk Manteuffel
Abstract: The selective excitation of individual characteristic modes for MIMO applications on an electrically large antenna structure is investigated. The characteristic mode analysis yields that a large number of modes is significant and thus basically suited for use in a multi-mode antenna. In order to find appropriate excitation arrangements for the individual characteristic modes, they are grouped according to their symmetry properties. It is found that characteristic currents belonging to the same group are correlated and thus cannot be excited separately, resulting in a reduced set of uncorrelated antenna ports.
