High-Performance Curved Reflectarrays for Telecommunication Applications

The use of curved reflectarrays for telecommunication applications is presented in this paper. For contoured beam applications, the curvature of the reflectarray surface can be used to enhance the bandwidth significantly, yielding reflectarray designs that are equivalent in performance compared to traditional shaped reflector antennas. For multiple spot beam applications, the curvature of the reflectarray surface can be used to enable the possibility of radiating more than one beam types in the 4-color frequency/polarization reuse scheme using a single feed. As a result, the number of main apertures needed to cover a multiple spot beam coverage can be reduced from four to two.
