  • Patent number: 7719463
    Abstract: The reflectarray comprises an array of patch elements (10-13). Each patch element has a cut ring shape formed of a conductive ring with at least one crossing gap. The outer diameter and inner diameter and crossing gap are adjusted so that a phase shift ? defined by the following relations is different from zero: ?(Eox)=?(Eix)+? (1) ?(Eoy)=?(Eiy)+?+? (2) where: ??(Eox) and ?(Eoy) are the phases of the orthogonal components and of the reflected wave, respectively, ??(Eix) and ?(Eiy) are the phases of orthogonal components and of the incident wave, respectively, ?? is a phase angle.
