Coupling in reflector arrays

In order to reduce the space occupied by a reflector array, it is desirable to arrange the array antennas as close to each other as possible; however, in this case coupling between the array antennas will reduce the reflecting properties of the reflector array. The purpose of the present communication is to demonstrate that this is true for a Van Atta reflector consisting of four half-wave dipoles arranged on a line. Theoretical results obtained by using the methods described in references are compared with experimental results. In contrast to previous experimental results which have been presented as normalized, the results described are absolute
