Abstract.  A dual-band multilayer shared aperture antenna (SAA) is presented, which can recognize anomalous two-dimensional beam steering simultaneously at two distinct operating wavelengths lie in near-infrared (NIR) (λ1=1055  nm) and visible (λ2=700  nm) spectra. The supercell consists of one large cross-shaped resonator antenna (top layer) and a 2×2 square-shaped patches (bottom layer). This compact bifunctional dual-band reflectarray SAA can steer the main beam toward relatively large angles (40  deg) in both θ- and ϕ-planes at dual-frequency bands. The state-of-the-art techniques in antenna design are exploited to attain the minimized aperture size and negligible coupling among NIR and visible arrays. The overall height of the antenna is 275 nm (0.25λ1). The presented structure is customizable in form and can easily be scaled to other frequency ratios.
