THREE DIMENSIONAL SUB-MM WAVELENGTH SUB-THZ FREQUENCY ANTENNAS ON FLEXIBLE AND UV-CURABLE DIELECTRIC USING PRINTED ELECTRONIC METAL TRACES

摘要

Novel methods for micro-additive manufacturing three dimensional sub-millimeter components are disclosed herein. The methods can include dispensing a dielectric at positions on a substrate so as to provide dielectric structures having an aspect ratio of up to 1:20. The methods can also include in-situ curing of the dielectric structure upon dispensing of the dielectric wherein the dispensing and curing steps provide for three dimensional configurations. Direct printing a metal nanoparticle solution on the dielectric to create conductive traces and thereafter sintering the printed nanoparticle solution so as to cure the conductive traces enables three dimensional conductive (antenna) elements having a length and width scale of down to 1 μm.

1. A method for manufacturing of a three dimensional sub-millimeter component, comprising:
dispensing a dielectric on one or more positions on a substrate so as to provide one or more dielectric structures having an aspect ratio of up to 1:20; in-situ curing of the dielectric structure upon dispensing the dielectric at the one or more positions, wherein the in-situ curing coupled with the dispensing of the dielectric provides for three dimensional configurations; direct printing a metal nanoparticle solution on the dielectric at the one or more positions to create one or more conductive traces; and hardening upon dispense and/or sintering thereafter the printed nanopowder solution so as to cure the conductive traces to form three dimensional elements, wherein the three dimensional elements have a length and width scale of down to 1 μm.
