Implementation of a multiple beamformer for coarse localization of passive UHF RFID tags

This study describes a testbed for coarse localization of passive UHF RFID tags by using a multiple beamformer network. The coarse localization is achieved by specifying the sector location of a tag and estimating its distance from the antennas. The multiple beamformer is composed of a four-element...
