A new scattering matrix of multiport antenna array

This paper deals with the mathematical model and properties of a new scattering matrix of given antenna array normalized to complex multiport impedance matrix of generators. The introduced scattering matrix is described a matching problem for a connection of array with multiport beamformer. The scattering parameters are based on eigenvalues and eigenvectors of the antenna multiport matrices. As shown there are an infinite number of the scattering matrices for given antenna array and multiport beamformer. The extremum properties of the Rayleigh ratio for the power maximization for multiport networks are used. The particular array and excitation network (signal divider) and results of computer frequency characteristic simulations are described.
