Abstract :
Flexible multi-layer inkjet printed capacitors that have a self resonant frequency above 3 GHz are demonstrated for the first time utilizing two custom formulated polymer-based dielectric inks. The formulation and characterization of both dielectric inks for optimal viscosity and film thickness are performed. The frequency dependent capacitance and quality factor (Q) are presented along with a study on the repeatability and measures to improve the quality factor of printed passives.
