Abstract

CàDIGO DE BARRAS DETECTÁVEL POR INTERROGAÇçO REMOTA, SISTEMA DE INTERROGAÇçO DE CàDIGO DE BARRAS, E, MÉTODO DE INTERROGAR UM CàDIGO DE BARRAS. Apresentados são um sistema e método para ler um código de barras legível por microonda formado de um padrão de material dielétrico. O padrão dielétrico cria um forte contraste de microonda com o meio circundante ressonando seletivamente com ou espalhando um sinal de microonda interrogante. Barras dielétricas podem ser fabricadas por impressão de jato de tinta, injeção, pulverização, desenho ou qualquer outra técnica. Informação de código de barras é codificada usando comprimentos diferentes, ângulos, ou posições de barras dielétricas. Um sistema de código de barras dielétricas legíveis por microonda inclui um código de barras fabricado de um material dielétrico, um transmissor com uma antena, e um sensor que sente o efeito produzido pelo código de barras dielétricas no sinal de microonda. O sistema de código de barras dielétricas pode usar múltiplos sinais de microonda que diferem em um ou mais aspectos, tais como polarização ou freqúência.
