Abstract

This article presents different high-frequency topologies implemented with fused filament fabrication (FFF) 3D-printing, using low-loss dielectric filaments and a low-cost 3D-printer. The proposed structures are three different graded index lenses, two dielectric leaky-wave antennas and a dielectric anisotropic polarizer. Good results are obtained in simulations and measurements in terms of bandwidth and radiation patterns, which shows that is possible to implement these structures even in millimeter wave bands, making it a cost-effective solution.
