Physical modeling of on-chip antenna for UHF RFID tags

Mass deployment of radio frequency identification (RFID) technology depends heavily on the reduction in tag cost and tag size. A revolutionary way to implement low-cost small-size tag is to integrate on-chip antenna (OCA) with tags. Applying tags embedded with OCA gains significant advantages not only in saving a major portion of the tag assembly cost but also in improving the system reliability and facilitating item-level applications.
