N2 - This paper reports on the development and evaluation of a reconfigurable millimeter-wave reflectarray based on liquid-crystal (LC) substrate operating in the D-band (105-125 GHz). The reflectarray is composed of a high-impedance surface with a meta-array of 33 × 29 patches on a 2-mm-thick quartz substrate, separated from the ground plane by a 40 μm-thick LC layer. A novel LC composition with low dielectric losses (< 0.003) and high dielectric anisotropy (> 1.3) has been developed for operation at millimeter-waves. The results demonstrate a reflection phase tunability of 210 degrees and low insertion losses of 2.5 dB. Furthermore, the device was demonstrated as a proof of concept for 1D beam-steering applications, exhibiting an operational bandwidth of 12 GHz.
