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) ( λ 1 = 1055 nm ) and visible ( λ 2 = 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 ( ≈ 0.25 λ 1 ). The presented structure is customizable in form and can easily be scaled to other frequency ratios.
