A biodegradable multi-platform tolerant passive UHF RFID tag antenna for short-life cycle IoT applications

Abstract

A biodegradable and cost-effective passive UHF RFID tag antenna for short-life cycle IoT applications is presented. The biodegradability and cost-effectivity is given by inking bioresorbable copper based paint on a bioresorbable cellulose based substrate. As a result, a relatively low cost antenna with good conjugate matching over the passive UHF RFID band and good dipole-like sensitivity read range pattern is achieved. Results showed 130MHz bandwidth and a long read range of 10.2m-12.7m when attached to several host objects of materials typically encountered in IoT applications. Hence, reasonably to be regarded as multi-platform tolerant. Simulations are corroborated by measurements and are in fairly agreement.
