摘要：
This communication proposes a novel unit cell for the design of dual-band dual-circularly polarized reflectarrays for space communications. The main advantage of the proposed cell is the use of one single layer for the antenna fabrication, hence yielding lower costs and fabrication with lower complexity in comparison to multilayer antennas. The proposed cell is used to design a dual-band dual-circularly polarized reflectarray with widely separated bands. Due to the physical symmetry, it provides very good polarization characteristics. The antenna performance is validated by far-field measurements and very good agreement between simulated and measured results has been verified.
