Design of Beamforming Conformal Antenna Array Based on Partially Reflecting Surfaces

A multi-faceted array using Partially Reflecting Surfaces (PRSs) for satellite communication is proposed. The beamforming algorithm is formulated using phase correction as well as amplitude weighting proportional to the level of embedded patterns in the direction of the scan. The pattern is effectively scanned within the field of view defined by the angular width of a facet. A fluctuation in maximum gain of less than 1 dB has been achieved, with a sidelobe level of -8.17 dB, though further research is needed to improve the sidelobe level.
