Compact Metal Mountable UHF RFID Tag on a Barium Titanate Based Substrate

The development of a compact metal mountable Radio- Frequency IDentiflcation (RFID) tag antenna on a ceramic substrate based on Barium Titanate is presented. The performance limitations and design trade-ofis of metal mountable RFID tag antennas are reviewed and the favorable features of a high-permittivity antenna substrate for the development of antennas for metal mountable RFID tags are discussed. The simulation-based tag antenna design process is outlined and the measured read range of the developed metal mountable tag on conductive platforms of various sizes is presented.
