Dual frequency selective reflectarray for propagation improvement

This paper proposes a novel dual frequency selective reflectarray that can control reflected beams independently at dual frequencies using two different polarizations. The reflectarray improves propagation by controlling the scattered beams to achieve high speed in broadband wireless mobile communication systems at a high frequency. The reflectarray comprises cross-dipole arrays and double square loops. Measurement and analysis results show the effectiveness of the reflectarray.
