[IEEE 2019 49th European Microwave Conference (EuMC) - Paris, France (2019.10.1-2019.10.3)] 2019 49th European Microwave Conference (EuMC) - Optimizing the Conductivity of Ink-Jet Printed Microwave Components on Polymer Substrates by Laser Sintering

摘要： In this work, microwave components were printed on a Kapton (polyimide) substrate using a Drop-On-Demand (DOD) ink jet printer with silver nanoparticle ink. Two different laser curing strategies are presented by implementing selective sintering. The measured improvement of the achieved conductivity is between 70 and 100% for such resonators from 5 to 15 GHz.
