Low-Cost Direct-Writing of Silver-Based Ink for Planar Microwave Circuits up to 10 GHz
Direct ink writing (DIW) of conductive ink is a printed electronics technology that allows a variety of electronic circuits to be produced in a simple way and with minimal waste of materials.In recent years it has been used for rapid prototyping of RF circuits typically working at S-band frequencies (2–4 GHz).In an attempt to extend this fre
