L'impression jet d'encre est une technique peu coûteuse adaptée à la fabrication d'appareils électroniques flexibles utilisant des solutions de nanoparticules conductrices sur une grande variété de substrats sans déchets de matériaux comme dans les techniques de gravure classiques. Dans ce livre, les antennes monopolaires coplanaires à large bande à profil bas fonctionnant à 20 GHz sont conçues et imprimées à l'aide d'encres à l'oxyde de cuivre et à nanoparticules d'argent sur des substrats flexibles. Le papier PET et Epson ont été les substrats flexibles choisis. Les effets de la modification de l'espacement des gouttes de l'encre sur la conductivité des films imprimés ainsi que sur les paramètres de l'antenne ont été entièrement étudiés par des simulations numériques et par des mesures. Une conductivité de 2,8 × 10^7 S/m a été trouvée pour les films de nanoparticules d'oxyde de cuivre imprimés sur PET en utilisant un espacement de chute de 20 µm conduisant à des performances d'antenne supérieures avec un gain et une efficacité atteints de 1,82 dB et 97,6 % respectivement. D'autre part, les antennes sur substrat en papier Epson montrent une perte de retour de -10 dB, bande passante qui s'étend de 17,9 GHz à 23,3 GHz, conduisant à une bande passante fractionnée de 26,0 %.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Inkjet printing is a low-cost technique suitable to fabricate flexible electronic devices using solutions of conductive nanoparticles on a large variety of substrates without material waste as in conventional etching techniques. In this book, low-profile wideband coplanar waveguide-fed monopole antennas operating at 20 GHz are designed and printed using Copper Oxide and Silver nanoparticles inks on flexible substrates. PET and Epson paper were the chosen flexible substrates. The effects of altering the drop spacing of the ink on the conductivity of the printed films as well as on the antenna parameters were fully investigated by numerical simulations and by measurements. A conductivity of 2.8×10^7 S/m was found for the Copper Oxide nanoparticles films printed on PET using a drop spacing of 20 µm leading to superior antenna performance with an achieved gain and efficiency of 1.82 dB and 97.6% respectively. On the other hand, antennas on Epson paper substrate show a -10 dB return loss, bandwidth which extends from 17.9 GHz up to 23.3 GHz, leading to a fractional bandwidth of 26.0%. 88 pp. Englisch.
