| 20100001079 | Combined EAS/RFID tag - A combined EAS/RFID tag including an EAS circuit and a first RFID circuit is disclosed. The EAS circuit has at least one capacitor and the RFID circuit has a main antenna wherein at least a part of the capacitor of the EAS circuit provides at least a part of the main antenna of the RFID circuit. The EAS circuit may include two capacitors and each capacitor may include first and second plates on first and second sides of a substrate wherein one plate of each capacitor forms part of the main antenna of the RFID circuit. | 01-07-2010 |
| 20090027208 | RFID Tag Containing Two Tuned Circuits - An RFID tag is disclosed adapted to be read by an interrogator including a reader antenna having a carrier frequency. The tag includes a first circuit including a first inductor and a first capacitor, wherein the first circuit is tuned to a frequency above the carrier frequency to compensate for detuning in the presence of a plurality of tags. The RFID tag includes a second circuit including a second inductor and a second capacitor wherein the first and second inductors are arranged to be coupled electromagnetically with a coupling factor less than unity and the second circuit is tuned to increase coupling between the first circuit and the reader antenna. A method of reading an RFID tag in the presence of a plurality of tags is also disclosed. | 01-29-2009 |
