Abstract:A novel wideband reflectarray antenna (RA) is designed for 5G millimeter (mm) wave communications in the frequency range of 26.5–36 GHz. The proposed unit cell is constructed using a grid periodicity of 0.52
${{\lambda }_0}{ }$
that offers 636° phase change through phase delay lines (PDLs) (
${{\theta }_{\text{s}}}$
). These PDLs are attached to the outer end of the unit cell comprising semi-circular rings. Bandwidth enhancement is achieved by incorporating … Show more
