A new dual-band reflectarray configuration

This paper presents a new configuration for dual-band linearly polarized reflectarray. Simulated phase responses are given in the paper. The radiating elements at two frequency bands are printed at the same layer. No physical contacts between elements will occur as the sizes of the elements are changing. Top layer blocking effects of the dual-layer configuration are also eliminated. The proposed configuration should be a suitable candidate for the dual-band reflectarray.
