Fully inkjet-printed multilayer microstrip patch antenna for Ku-band applications

A fully inkjet-printed multi-layer microstrip patch antenna with a CPW to microstrip line transition is designed and demonstrated for the first time in this paper. Both metallic layers and SU-8 substrate are fabricated with an additive inkjet printing process. The patch antenna is designed to operate at 14 GHz, and the operation of the antenna is confirmed in measurement validating that fully additively-processed RF devices are a new option for post processing RF devices with substrate independence.
