|In the design process of array antennas, coupling is one of the most important elements to be considered. The real feeding-radiated coefficients can be quite different from the theoretical ones because of this effect. In this paper, a characterization method is presented that allows each element to be matched from the array. All the parameters of the array-coupling model are obtained through the measurement of scattering parameters and radiation patterns. Two practical applications for a linear patch array are presented.
