ELECTROMAGNETIC ANALYSIS AND CAD MODELLING OF AN RF-ID SYSTEM
Abstract
Radio Frequency Identification (RF-ID) is a key technology in today’s logistics and industrial scenarios, used for labelling and tagging items in warehouses and industrial production. In order to avoid unexpected faulty behaviours, some working conditions and setup parameters of RF-ID systems need to be carefully checked. To this aim, both measurements and numerical simulations can advantageously be performed. In this paper, some key working conditions are described and analyzed in terms of coupling between the reader device and RF-ID tags. In particular, the reading range in space of a standard inductive coupling 13.56 MHz RF-ID system is analyzed by using numerical simulations of scattering parameters and CAD (Computer Aided Design) modelling. The purpose is to present an example suggesting how to efficiently perform such a kind of analysis in order to verify the effectiveness of a RF-ID system setup.
