Title: LIQUID-CRYSTAL RECONFIGURABLE MULTI-BEAM PHASED ARRAY RELATED APPLICATIONS
Abstract:
A phased array antenna comprising a two dimensional array of lens enhanced radiator units, each radiator unit comprising: a radiator for generating a radio frequency (RF) signal; and a two dimensional phase variable lens group defining an aperture in a transmission path of the RF signal, the lens group comprising a two dimensional array of individually controllable lens elements enabling a varying transmission phase to be applied to the RF signal across the aperture of the lens group. Also, a unit cell of a lens element in a metamaterial sheet, the unit cell comprising a stack of cell layers, each cell layer comprising a volume of nematic liquid crystal with a controllable dielectric value enabling each cell layer to function as tunable resonator.
