All-dielectric Terahertz waveguides based on hollow-core EMXT fiber are fabricated via THz rapid prototyping using polymer jetting technique. Several waveguides of identical cross-section and differing lengths are characterized by THz time-domain spectroscopy (THz-TDS) to extract the waveguide intrinsic propagation loss. Measurement results agree very well with simulation. This as an initial example demonstrates a waveguide with low propagation loss of 0.03 dB/mm at 105 GHz. Based on the waveguide, an EMXT antenna is also formed by modifying the defect shape into a horn. Simulation shows good performance of this horn antenna. The antenna is fabricated by the same rapid prototyping method, and its far-field pattern measurement is currently undergoing. © 2010 IEEE.
