Automated-reading process of an RFID reader can be interrupted due to the relative orientation of the transponder (tag) antenna with respect to the reader antenna. This article proposed a modified revolving magnetic field based RFID reader, which is capable to produce a rotating near field in space. When a magnetically coupled RFID tag placed in the near field zone or read range, the tag can easily...
As a core technology, RFID technology has been more and more widely used with the development of Internet of Things. But in current RFID applications, there is a key problem waiting to be solved. That is, how to make the reader read better? For this problem, we propose a method for optimizing the position of passive UHF RFID tags. Firstly, a relative ideal test environment has been built. And then,...
In many RFID application scenarios the distance between reader and tags is constantly changing with a different velocity. And this change will affect the performance of RFID system. In this paper, a novel scheme named a dynamic RFID performance test system is proposed to find out how movement affects the performance of the RFID system. A new simplified model is proposed to describe these scenarios,...
Adopting an innovative technology often requires extensive intelligence research. A major value indicator for RFID Technology adoption is how the potentials of RFID can translate into actions to improve business operational efficiency [1]. This paper presents a Local Association Network (LAN) approach to developing RFID enabled visibility systems for body tagging. On site testing validates the proposed...
This paper proposes a new technique to modify the original design of a known antenna according to the requirement of a new chip with an input impedance different from the first design This methodology is based on the idea of creating a database with antenna simulations and use Artificial Neural Networks (ANN) as a tool for selection of the appropriated configurations necessary for a better performance.
