A theoretical investigation of a square Van Atta reflector consisting of half wave dipoles mounted above and parallel to a conducting plate was carried out. Each pair of antenna elements was represented by an equivalent circuit, using x-circuits for the transmissionlines. The mutual impedance between the antenna elements and the reradiation both from the elements and from the plate was taken into account. The influence of the conducting plate was treated by using the theory of images. The scattering cross section of the reflector was examined analytically and numerically. The numerical results were compared with experimental results obtained by others.
