Broadband design of three-layer printed reflectarrays

A method is proposed to design three-layer printed reflectarrays with patches of variable size for broadband operation. The patch dimensions are adjusted by an optimization routine to achieve the required phase distribution in a given frequency band. A 1-meter reflectarray was designed, and significant bandwidth and gain stability improvements were obtained.
