Abstract. This paper describes the development of a reflectarray cell based on the combination of a patch antenna and a coplanar band-stop filter. This approach permits to control reflection phase distribution on the reflector while reducing narrow-band radar cross section and it allows reconfigurability using MEMS capacitive switches.
