Abstract

A smart passive RFID reader includes an RFID reader, a microcontroller providing a means for increasing the probability of detecting correct passive RFID tags and decreasing the probability of detecting incorrect passive RFID tags, and antennas connected to the RFID reader, wherein adjacent antennas have orthogonal polarization and the antennas each have a pivoting axis, whereby rotating the antennas about their pivoting axes causes a change in the overlap of the antenna beam radiation patterns and thereby provides a means for adaptive beamforming in order to improve tag reading.
