Design, simulation, fabrication and measurement results of 3D-printed Fresnel lens and helical antenna are presented. Because the real and imaginary permittivity of the 3D-printed material (Polylactic Acid) at the frequencies of interest were unknown, we have measured these properties using time-domain spectroscopy as well as impedance/material analyzer. Full-wave simulation was used to design and optimize the realized gain of the lens and helical antenna. These devices were later on fabricated using fused deposition modeling and stereolithography, respectively. The gain pattern measurements were then performed in the anechoic chamber. Measurement results showed that the lens could achieve a gain improvement of 8-9 dB at 30 GHz. Furthermore, a 3D-printed helical antenna with suspended microstrip was shown to achieve a gain of 14 dB and half-power beam width of 30°, which closely agreed with the simulated data. By designing, fabricating and characterizing the two aforementioned examples, the limitation and challenges associated with additive manufacturing for antenna applications were studied. Moreover, our study will advance realization of antenna structures, specifically in the millimeter wave band.
