Evaluation of the quiet zone generated by a reflectarray antenna

In this work, the quiet zone achieved by a reflectarray antenna is evaluated. The study is focused on obtaining the near field generated by the reflectarray and the evaluation of the quiet zone in terms of the design parameters of the reflectarray antenna is presented. Then, the most critical parameters in the design of the quiet zone are identified. Finally, the quiet zone generated by the reflectarray is compared with that obtained by a classic parabolic reflector.
