A novel wide-angle beam-scanning phase synthesis method, namely, multibeam phase matching method is introduced in this paper. It takes full advantage of angle sensitivity characteristic of reflectarray elements to improve the beam-scanning performance of reflectarrays. In the process of reflectarray...
