Coupling estimation and compensation model for arrays of multimode radiators

In the design process of array antennas, coupling is one of the most important aspects to be considered to complete a realistic model. The real feeding radiated coefficients can be quite different from the theoretical ones because of this effect. A characterization and compensation model is presented. This procedure is able to match each element from the array. All the parameters of the array coupling model are obtained through scattering parameters and radiation pattern measurements. Some practical applications to linear patch arrays are presented.
