Abstract :
Summary form only given, as follows. A 3D Luneburg Lens was designed, fabricated and characterized. Refractive index control is based on the mixing ratio of air voids and polymer. The lens is designed to work at X-band. Effective permittivity is calculated by Ansoft HFSS. Fabrication is implemented by a polymer jetting rapid prototyping method. In the measurement, the lens antenna is fed by an X-band waveguide. Half-power beamwidth of the antenna is 14 degree, no obvious sidelobe is found in the measurement above the noise floor.
