| abstract |
An RFID system including a reader which radiates a query signal and one or more passive multiple-port tags, each comprising multiple antenna ports; each tag includes at least two chips connected to the same antenna or each to a different antenna, so that the port impedance of each chip is different, in such a manner that the features of the reply signal of each chip allow to detect one or more physical-chemical or geometric parameters of the target on which the multiple-port tag is applied, said parameters affecting both the reception of the query signal and the emission of the reply signal. |
