Abstract
Radio frequency identification (RFID) tags are described that include a substrate, an antenna disposed on a major surface of the substrate, an integrated circuit (IC) disposed on a major surface of the substrate, and one or more stand-alone capacitors disposed on a major surface of the substrate. The antenna may have a length less than about 2 meters between first and second ends of the antenna. The integrated circuit may have an effective capacitance less than about 1000 pF and the one or more stand-alone capacitors may have an equivalent capacitance greater than 500 pF and may be connected in parallel with the antenna and the IC.
