Abstract
Methods, apparatuses and systems for an RFID system are disclosed herein. An example system may include one or more of antennas, each antenna including an RF power comparator for comparing the power level indicator of the RF signal of the antenna with an RF signal power threshold, a bias voltage comparator for comparing a bias voltage of the antenna with a bias voltage threshold, an RF fault bypass circuit functioning as an approximate open circuit when the bias voltage of the antenna is equal to or higher than the bias voltage threshold, and as an approximate short circuit when the bias voltage of the antenna is lower than the bias voltage threshold. The RFID system may include an RFID reading circuitry for determining a fault in the RFID system using any of the RF power comparison, bias voltage comparison, and function of the RF fault bypass circuit.
