Design of antenna with Ku/Ka-band and dual-beam based on 3D printing

A 700mm diameter 7-layered hemisphere Luneburg lens antenna with radically drilled holes structure using paraffin reinforced polystyrene based on 3D printing is proposed. Operating at Ku/Ka band, the antenna can simultaneously aim at two targets. With high performance, the lens antenna effectively solves the processing difficulty and anisotropy of traditional processing method, and easily realizes superior performance through using lower dielectric loss materials.
