Suppression of Scattered Fields in a Van Atta Reflector Response

摘要

This letter proposes a simple but effective method to suppress scattered fields in a Van Atta reflector response by providing a displacement of one-quarter-wavelength between the two sub-arrays composing the reflector. The validity of the present method is verified through an experiment conducted at 1.27 GHz band using a prototype 8-element Van Atta reflector.
