Electronically Re-Configurable, Non-Volatile, Nano-Ionics-Based RF-Switch on Paper Substrate for Chipless RFID Applications
Résumé
This article reports the first results of a Nafion® based solid state Non-Volatile 13 electronically reconfigurable RF-Switch integrated to a Co-Planar Waveguide transmission line 14 (CPW) in shunt mode, on flexible paper substrate. The switch is based on a Metal-Insulator-Metal 15 structure formed respectively using Silver-Nafion-Aluminum switching layers. The presented 16 device is fully passive and shows good performance till 3GHz, with an insertion loss less than 3dB 17 in the RF-On state and isolation greater than 15dB in the RF-Off state. Low power DC pulses in the 18 range 10V/0.5mA and-20V/0.15A are used to operate the switch. The device is fabricated in an 19 ambient laboratory condition, without the use of any clean room facilities. A brief discussion on the 20 results and a potential application of this concept in a re-configurable chipless RFID tag is also 21 given in this article. This study is a proof of concept, of fabrication of electronically Re-Configurable 22 and disposable RF electronic switches on low cost and flexible substrates, using a process feasible 23 for mass production. 24
