Abstract

In this paper millimeter-wave reflectarray research, simulation and measurements results are presented. Waveguide elements were used as reflectarray unit cell. Exponential horn was used as illuminator. Low profile reflectarray transforms wavefront like a conventional parabolic reflector. The reflectarray aperture, supporting structure and illuminator were fabricated from aluminum alloy by CNC machine. Measured results show very good agreement with characteristics obtained from the simulations. Manufactured reflectarray provides 50% efficiency in 10% bandwidth.
