Printed Microwave Connector
This paper describes the development of a printed, planar microwave connector operating from 1-7 GHz. The connector, which is based on a Grounded Coplanar Waveguide (GCPW) transmission line structure, is fabricated using 3D-printed thermoplastic material (PEEK) and conductive nanoparticle silver ink. Electromagnetic models were established to provide guidance on design tradeoffs and their impact on microwave performance. New mechanical designs were also developed to provide accurate alignment and robust connection of the two halves of the planar connector structure. Initial connector prototypes were fabricated to validate the new planar design using conventional double-sided copper laminates (Isola MT40). The designs were then implemented in an all-printed version of the connector. Electromagnetic models of the printed connectors were developed using the measured dielectric properties of printed PEEK. The insertion loss of the printed connectors was measured to be less than 1.7dB across the band.
