Abstract
This work presents a coaxial transmission line constructed with additive manufacturing (3D printing) technologies. The coaxial structure is primarily air dielectric and, thus, is relatively low loss and is capable of high frequency transmission, demonstrating good transmission above 10~GHz. Additionally, a first order band-pass filter is demonstrated along with a comparison to an equivalent planar (microstrip) filter. This process provides a template for designing coaxial interconnects which is far cheaper and flexible for the designer than traditional methodologies. The loss of the completed design is measured to be 0.78~dB in a 50~mm long section at 10~GHz (0.16~dB/cm). Simulated and measured results are shown.Keywords
