Passive UHF RFID System Evaluation for Retail

Radio Frequency Identification (RFID) is an automatic identification method that allows an object to store and communicate unique information using RFID labels/ markers. These labels - more often referred to as "Tags" - which describe unique features of the object to which they are attached, can be read several meters without the need to be in the line of sight of a reader. Passive UHF RFID technology has been perceived to have a significant development in the next decade due to the accelerated growth of sophisticated technological devices. This development is largely driven by the fields of industry and retail.

The identification of items by RFID-UHF C1G2 technology is increasingly used in wholesale and retail trade. This is particularly due to the reduction in the cost of tags produced in large volumes (around 10 cents). Their reading distance performance in laboratory conditions easily reaches about ten meters. A passive label is considered activated when it is in the reader field, so when it receives enough power for the chip to wake up. In a UHF passive RFID system, the forward link is limited by the tag sensitivity.

Given a specific positioning of the antenna, the UHF RFID system’s performance could be enhanced in a store environment due to other paths that might increase the detection probability or lessen the limitation on the path losses. It must be precised however, that multipath fading or frequency selective fading, the fading amplitude depends on the frequency and the polarization.
