Abstract :
In the design process of array antennas, coupling is one of the most important elements to be counted. The real feeding radiated coefficients can be quite different from the theoretical ones because of this effect. A compensation method is presented allowing matching of each clement of the array. The parameters of the array coupling model are obtained through the measurement of the radiation pattern of the elements without the feeding network. An application to a linear patch array is presented as an example.
