Reflectarrays mounted on or embedded in cylindrical or spherical surfaces

摘要

In this paper, reflectarrays mounted on or embedded in cylindrical or spherical surfaces are designed, analyzed, and simulated at 11.5 GHz for satellite applications. The effect of the cylindrical or spherical surfaces curvature with different subtended angles on the radiation characteristics of the designed reflectarrays are investigated and compared with that of planar reflectarray. Full-wave analysis using the finite integration technique (FIT) is applied. The impedance matching bandwidth is greater than 3 GHz. The results are validated by comparing with that calculated by transmission line method (TLM).
