A fully-3D-printed complementary right/left-handed transmission line

In this effort, a full-3D design of a complementary right/left-handed (CRLH) transmission line structure with a transition frequency of 7.5GHz, which takes advantage of the unique capabilities of additive manufacturing technologies (AMT) is presented. A fully-additive fabrication process, combining SLA dielectric and aerosol conductor printing, is utilized. The fabricated CRLH structure is shown and measured. The approaches reported in this effort may set the foundation for the emergence of novel exotic metamaterial structures, enabled by the unique manufacturing capabilities of AMTs.
