A method to fabricate continuously tapered antireflective (AR) coatings using fused deposition modelling (FDM) is presented. The method leverages FDM's ability to fabricate spatially varying 3D structures with variable polymer fill volumes, thus producing a spatially varying effective permittivity profile. The method is validated experimentally within the Ka-band. Experimental results closely match...
A low-profile antenna that includes an integrated artificial magnetic conducting (AMC) ground plane is presented and is fully fabricated using multi-material additive manufacturing. It is shown that combining standard fused deposition modelling with conductive micro-dispensing printing enable one to realise mechanically robust antenna systems that contain spatially variable dielectric properties and...
