Antennas fabrication for RFID uhf and microwave passive tags
Abstract
In this paper, the authors present several antenna structures for RFID passive tags with direct chip connection. In this study, the substrate is PET (Polyethylene terephthalate) with 80μm thickness, the conductive layer is copper with 10μm thickness and CST Microwave Studio is used for simulation. The antenna design process is described and related results are shown. The goal of this study is to achieve compact size, good matching impedance, and to increase the bandwidth and read range of the tag as much as possible. The prototypes were fabricated by sputtering technology with 1μm thickness, then thickened by electroplating technique and finally tested by hand-held reader for read range characterizations.
