Dual-band X/Ku Reflectarray Antenna Using a Novel FSS-Backed Unit-Cell with Quasi-Spiral Phase Delay Line

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
A novel FSS-Backed reflectarray unit cell is introduced to design a dual-band X/Ku Reflectarray Antenna (RA). A Ku-band RA based on this FSS-Backed cell element is designed and located on the top of a conventional X-band RA.
