Abstract

A new printed antenna is proposed as a passive tag for UHF Radio Frequency Identification (RFID). The proposed antenna has a size significantly smaller than a printed dipole antenna working in the same UHF frequency band. Nevertheless, its operating bandwidth is quite large, since it encompasses all worldwide UHF RFID bands, and extends well beyond at both edges. The antenna has been designed using a general purpose 3D CAD, CST Microwave Studio, and measured results are in very good agreement with simulations. The proposed passive RFID tag meets both the objectives of low-cost and size reduction.
