Abstract:

An experimental investigation of a linear Van Atta reflector consisting of four half-wave dipoles was made in a radio-anechoic box. In agreement with a theoretical and numerical investigation, the experiments show that the reflector has the effect stated in Van Attas patent description only to a limit extent. It was confirmed that maximum reflection in many cases is not back in the direction of incidence and that the reflector has a mirror effect to the same extent as it has the Van Atta effect. Furthermore it was verified that for certain lengths of transmission lines and angles of incidence there is no reflected field. Asymmetries in the reradiation patterns were observed which, according to theory, are due to mutual coupling between the dipoles.
