摘要
A passive difference-frequency tag including a first antenna on a substrate, the first antenna having a first frequency band, the first antenna having a first shape of a first bowtie with first rounded end caps and first ends opposed to each other. The passive difference-frequency tag also includes a second antenna on the substrate inside the first antenna. The second antenna has a second frequency band higher than the first antenna frequency band. The second antenna having a second shape of a second bowtie with second rounded end caps and second ends opposed to each other. A combination of the first antenna and the second antenna forms a plurality of multi-band antennas with a shared axis of symmetry. The passive difference-frequency tag also includes a diode assembly on the substrate, and connected to the first ends of the first antenna and to the second ends of the second antenna.
