This paper demonstrates the feasibility to manufacture high performance radio-frequency passive components on cellulose substrates by exploiting two novel technologies: the vertically integrated inkjet printing and the copper laminate method. Both processes are substrate independent and thus suitable for fabricating circuits on paper as well; moreover, in a future perspective, they can be easily combined together in order to exploit their complementarity. Passive components such as capacitors and inductors, with Qs up to 22, never registered before on cellulose substrates, and Self-ResonantFrequency (SRF) up to 4 GHz are described. The obtained values of the capacitance and inductance per unit area are 0.8 pF/mm2 and 43 nHlmm2, respectively.

Abstract
This paper demonstrates the feasibility to manufacture high performance radio-frequency passive components on cellulose substrates by exploiting two novel technologies: the vertically integrated inkjet printing and the copper laminate method. Both processes are substrate independent and thus suitable for fabricating circuits on paper as well; moreover, in a future perspective, they can be easily combined together in order to exploit their complementarity. Passive components such as capacitors and inductors, with Qs up to 22, never registered before on cellulose substrates, and Self-ResonantFrequency (SRF) up to 4 GHz are described. The obtained values of the capacitance and inductance per unit area are 0.8 pF/mm2 and 43 nHlmm2, respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
