Resumo: Abstract 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. Actually, the band-stop Frequency Selective Surface (FSS) property is applied to a wideband element to create isolation between X and Ku band RAs which utilizing the same radiating element. A wideband cell element with attached quasi-spiral phase delay line is employed for phase compensation in both bands. As a FSS-backed cell element, the remarkable feature of the proposed dual band unit cell compared to previous works is its possibility of operation in closer frequency bands in comparison with other dual band FSS-backed RAs. Two reflectarrays with aperture size of 7.65λ×7.65λ and 7.35λ×7.35λ are designed, fabricated and measured for X band and Ku band, respectively. Measured results show 1-dB gain bandwidth of 12% for X band and 11% for Ku band which demonstrate wideband operation of this dual-band reflectarray antenna.
