Abstract

ANTENA E SISTEMA DE IDENTIFICAçãO POR RADIO FREQüêNCIA Uma antena de múltiplos circuitos fechados é descrita tendo uma pluralidade de circuitos fechados condutivos para produzir um campo eletromagnético para comunicação de identificação por radio freqüência (RFID) com etiquetas de RFID. Os circuitos fechados condutivos são separados por pelo menos uma distância que é selecionada com base em uma dimensão das etiquetas de RFID com as quais a antena se comunica. Desse modo, os circuitos fechados são posicionados e espaçados de uma maneira que reduz o tamanho dos vazios dentro do campo magnético resultante. Adicionalmente a configuração da antena de circuito fechado duplo aumenta a cobertura da antena, e diminue a capacitância inter-enrolamento, aumentando, assim, o alcance global de leitura obtido pela antena.
