Design of cylindrically conformed metal reflectarray antennas for millimetre-wave applications

Abstract

Conformal metal reflectarray antennas on the surface of a cylinder are designed for millimetre-wave applications. All depths of metal grooves in the reflectarrays are specially manipulated for high-gain conformal reflectarray antennas. There is a good agreement between simulated and experimental radiation performance results for two different 'sagittas'. The proposed conformal reflectarray antennas can be a helpful choice for applications requiring high-gain antennas on curved platforms.
