Abstract

ELEMENTO COMPENSADOR, ETIQUETA DE IDENTIFICAçãO POR RADIOFREQüêNCIA, E, SISTEMA DE IDENTIFICAçãO POR RADIOFREQüêNCIA Etiquetas de identificação por radiofreqüência (RFID) incluem elementos compensadores. Os elementos compensadores aumentam a operação de uma etiqueta de RFID compensada, até mesmo quando em proximidade íntima a outras etiquetas de RFID, se as outras etiquetas são compensadas ou não compensadas. Os elementos compensadores podem incluir um laço fechado de material conduitivo adicionado a uma antena de etiqueta de RFID. O laço condutivo compensa o desempenho de etiqueta de RFID quando múltipas etiquetas de RFID estão em proximidade íntima, mantendo a resposta de freqüência do grupo montado de etiquetas substancialmente centrada perto da freqüência operacional do sistema de RFID.
