title = "Frequency Scanning Reflectarray Based on Composite Right/Left-Handed Transmission Lines",
abstract = "This paper presents a new design method, based on composite right/left-handed (CRLH) transmission lines (TLs), to realize frequency scanning reflectarrays. The proposed technique enables continuous steering of the reflected beam toward both positive and negative elevation angles, by simply connecting customizable progressive phase advance/delay lines to the existing delay lines of a broadband reflectarray. This unique feature would otherwise not be possible using conventional right-handed delay lines due to impractical physical lengths and lack of control over the phase slope. A small prototype array of 4 × 3 elements operating at a center frequency of 2.5 GHz is designed, fabricated, and measured to demonstrate the frequency scanning enhancement provided by the CRLH TLs.",
