RFID TAG system has two main variables—TAG‐voltage and TAG‐voltage derivative with respect to time which may be subject to delay as a result of electromagnetic interferences
There are two main RFID TAGs variables which are affected by electromagnetic interferences‐‐ voltage developed on the RFID Label and the voltage time derivative
Summary
This article discusses a very critical and useful subject of passive RFID TAGs system stability analysis under electromagnetic interferences. RFID TAG system has two main variables—TAG‐voltage and TAG‐voltage derivative with respect to time which may be subject to delay as a result of electromagnetic interferences. The stability of a given steady state is determined through the use of the graphs of a function of τ1, τ2, which can be expressed distinctly and can be depicted by Matlab and other popular software‐‐we need only look at one such function and locate the zeros. This function often has only two zeros, providing thresholds for stability switches. The analytical criteria provided for the first and second order cases can be used to obtain insightful analytical statements and can be helpful for conducting simulations
