Abstract :
This paper presents an improvement of the read range, radar cross section (RCS) and reliability of radio frequency identification (RFID) tags using multiple antennas. Measurements were performed using custom built, semi-passive RFID tags with co-planar segmented-loop antennas. Results show an increased read range as compared to RFID tag with single segmented-loop antenna.
