Mutual coupling between linear dipoles in an array environment

The influence of parasitic elements to self and mutual impedance is found through the idea of generalized impedance matrix in this paper. Extra ports are defined on the element to take into account the surface current on the open-circuited parasitic elements. A 3 by 3 array of dipole antenna is analyzed to verify the efficiency of this method. The idea might also be extended to analyze arrays of microstrip patch antennas.
