Automatic Testing System for UHF Passive RFID Tag Performance

Abstract

With the advancement of Radio Frequency Identification technology, various RFID products are emerging in our life. More and more government agencies and retailers have realized the potential of RFID technology and have mandated or recommended their suppliers to attach RFID tags to their products. The tag performance highly determines implement of these mandates and recommendations. In this paper, we discuss an Automatic testing system for UHF passive RFID tag performance. Both hardware and software architectures will be presented.

Design and Implementation of Double-Transmitter-Coil Antenna Used for the Tag Test System

“…This paper designs a new DTC antenna which can perfectly solve the problems existed in traditional STC antenna and can be better applied to the tag detection systems. Besides, the DTC antenna can be also used for estimating Veff of tags [3].…”

Performance and Benchmarking of Multisurface UHF RFID Tags for Readability and Reliability

“…The work by [5] considered maximum range and orientation sensitivity but did not take into consideration the medium on which the tag is put. Reference [6] proposed a method where the system can test the UHF RFID tag's performance to support RFID performance benchmarking automatically and efficiently and to help the user in proper selection of tags for their application. Reference [7] proposed a generalized parameterization of the three-dimensional reading range which can be applied to planning and optimization of readertag network.…”

“…For tag testing, 10 samples of each tag type were taken and evaluated for different orientations (4), different medium (3), and different distances (6), which constitutes 7200 readings. A tag is taken and is tested for readability at different distances and different orientations and on different mediums which are air, cardboard, and metal sheet.…”
