This conference paper presents a dual-band aperture-shared Fresnel zone plate (FZP)-based lens antenna for the V-band and D-band applications using conductive and dielectric fully-integrated 3D printing. In contrast to traditional full metal-based structures, double-screen grid structures are used to implement the concentric opaque rings of the FZP. Since the grids provide different transmission/reflection features at dual-band, they will not influence each other. A dielectric ring is directly printed atop the FZP for compensating for the phase-shifting from the grids. An antenna prototype is fabricated and measured. The radiation performance agrees well. The peak gains achieved are 20.3 dBi for the V-band and 21.9 dBi for the D-band, respectively.
