    • 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.
    • 公开了一种适于被包括具有载波频率的读取器天线的询问器读取的RFID标签。 标签包括包括第一电感器和第一电容器的第一电路,其中第一电路被调谐到高于载波频率的频率以补偿存在多个标签的失谐。 RFID标签包括包括第二电感器和第二电容器的第二电路,其中第一和第二电感器被布置为以小于1的耦合因子电磁耦合,并且第二电路被调谐以增加第一电路和读取器之间的耦合 天线。 还公开了在存在多个标签的情况下读取RFID标签的方法。
