Design of complementary reflectarray
Electronics Letters, 2014 A novel solution for the manufacture of a reflectarray antenna is presented. The unit cell simply consists of dielectric foam inserted between two thick metallic plates. The plate illuminated by the feeder is a 0.5 mm‐thick stainless steel sheet into which the C and the reverse C slots are laser cut.
