Abstract
High interference and low read rate have repeatedly been reported by radio frequency identification (RFID) consumers as the main drawback of passive RFID technology. We investigate a solution to this problem by employing low scattering antennas. We propose a new state of scattering state for RFID tags in that tags will switch to low scattering states to suppress their interference to an established and ongoing backscattering link between an RFID reader and a target tag. We evaluate the efficiency of our proposed solution by random deployment of tags in a network of ten antennas. We show that by using our proposed solution the read rate is 93.76% when the threshold of detecting signal at the reader is set to 0.75δ where δ is the magnitude of the backscattered signal from the target antenna when it is alone in the field.
