High-quality flexible antenna fabricated by ion-exchange technique

摘要: Abstract In this work, low-cost ion exchange technique coupled with printed-mask method has successfully been applied on the fabrication of high-quality flexible antennas. Nano-silver particles are chosen as conductive material CPW-fed antenna. The structure antennas is well-defined by inkjet printing method. experimental results indicate that a compact, smooth and highly-defined silver pattern formed PI film thickness 800 nm, particle size 50 nm sheet resistance 2.34 Ω/sq. A peak gain 42.68 dB at resonant frequency 2.4 GHz nicely accords simulated result ANSYS Electronics, demonstrating desired impedance matching can be realized. Moreover, PI-based antenna shows excellent flexibility low sensibility to bending tests. Therefore, patterned printed mask suitable for wireless electronics devices such wearable devices, RFID labels mobile communication.
