A scheme for a theoretical investigation of a square Van Atta reflector consisting of half-wave dipoles with a conducting plate parallel to the plane of the dipoles is given. The reradiation pattern of the reflector has been examined both analytically and numerically and the results have been compared with experimental results obtained by others. The influence of the presence of the plate and of changing the values of the parameters has been investigated. A theoretical examination concerning the dependence of the reradiation pattern on the parameters of a four-element linear Van Atta reflector has been performed and a numerical optimization of the reradiation pattern has been carried out. The possibility of using the technique of dynamic programming to determine the dimensions of antenna arrays with prescribed properties, especially Van Atta reflectors, has been examined.
