Wideband reflectarrays using artificial impedance surfaces

The gain bandwidth of a microstrip reflectarray can be substantially improved by replacing the usual layer of near-resonant patches with a simple artificial impedance surface consisting of closely spaced electrically small patches on a grounded dielectric substrate. It is shown that this approach ca...

Zusammenfassung:The gain bandwidth of a microstrip reflectarray can be substantially improved by replacing the usual layer of near-resonant patches with a simple artificial impedance surface consisting of closely spaced electrically small patches on a grounded dielectric substrate. It is shown that this approach can lead to reflectarray gain bandwidths (1 dB) in excess of 20% with a single layer of printed elements.
