An investigation of curved contoured beam reflectarrays with reusable surface for multiple coverages is presented. The main advantage of curved reflectarrays over shaped reflectors is that they allow the possibility of reusing a standard parabolic mold for multiple missions. To demonstrate this, two curved reflectarrays are designed using the direct optimization technique to fulfill the requirements...
This paper presents the analysis and optimization of a 1 meter single-layer curved contoured beam reflectarray in Ku-band. The curved reflectarray is designed to radiate a contoured beam over a European coverage in both transmit and receive frequency bands for dual linear polarization. For the analysis of the curved reflectarray, the spectral domain method of moments assuming local periodicity is...
The design and optimization of a single-layer multi-faceted dual-polarization contoured beam reflectarray with different coverages in each polarization has been presented. The reflectarray is optimized using a direct optimization technique to produce a contoured beam for a European coverage in H-polarization and a contoured beam for Brazilian coverage in V-polarization in a 10% bandwidth.
