Abstract
ABSTRACTFor passive RFID sensor tag, high sensing sensitivity is achieved at the expense of read range reduction with a fixed transmitted power of RFID reader. To maximize sensing sensitivity and ensure satisfied communication performance of tag at meanwhile, the constraint between them can be defined as a multi‐objective problem. The MOEA/D‐DE (multi‐objective evolutionary algorithm based on decomposition combined with differential evolution) is applied for the first time to provide a direct and effective solution to this constraint. For demonstration, an effective permittivity sensor and a temperature sensor are designed with MOEA/D‐DE, respectively. Both the simulated and measured results show the feasibility of applying MOEA/D‐DE to design high‐sensitivity sensor tag with satisfied communication performance. © 2016 Wiley Periodicals, Inc.
