  • Design and Additive Manufacture of Multi-Tapered Coaxial Baluns

    by Kyle P. McParland, Mark S. Mirotznik

    In this paper, a new design method is introduced for wideband transitions from an unbalanced coaxial feed to a balanced two wire port. The device expands upon the traditional tapered coaxial balun by allowing for variations of both the inner and outer conductor radii in addition to the slot width. This multi-tapered approach provides additional design freedoms useful for realizing a wide range of impedance ratios, satisfying fixed geometrical constraints, and reducing transmission losses. A multimaterial additive manufacturing (AM) approach is described for fabricating the balun’s complex three-dimensional geometry. Experimental validation was conducted within the Ku-band for printed back-to-back baluns and an integrated antenna feed that combined a printed connector, a multi-tapered coaxial balun, and a spiral antenna. Simulated and measured results showed good performance over the frequency band of interest.


  • Additive Manufacture of Custom Radiofrequency Connectors

    by Kyle Mcparland, Zachary Larimore, Paul Parsons, Austin Good, John Suarez, Mark Mirotznik

    We present the design and characterization of fully additively manufactured (AM) SubMiniature version A (SMA) connectors for use up to 18 GHz. Three-dimensional printed connectors can be directly integrated into the radio-frequency (RF) circuit without post-process bonding and can be fabricated into unusual shapes. The flexibility this affords in the manufacturing process offers significant advantages, especially for applications that need to meet strict size and volume constraints. To that end, we describe modifications to the traditional SMA design that better enable AM fabrication. A variety of different connector geometries were printed and fully characterized both electromagnetically and mechanically. Experimental measurements up to 18 GHz demonstrated good RF performance with low insertion losses (< 0.5 dB). Mechanical testing showed that the printed connectors could withstand up to 4.5 kg of direct force for extended periods of time without damage to the printed threads or other connector parts. Additionally, the printed connectors demonstrated good RF performance after repeated use.
