Abstract

We present a fully printable, planar, orientation independent, single layer, chipless RFID tag. The tag consists of a circular patch with multiple discretized circular slot resonators nested in it. This design reduces the total size of the tag since the discrete circular slot resonators resonate at a lower frequency than perfect circular resonators for the same diameter. Reader´s complexity is reduced as the tag is polarization independent, improving the tags readability from different angles with respect to the reader antenna. Its single layer characteristics make this tag a potential candidate for conductive ink printing. The frequency band is within 6 to 14 GHz.
