Abstract: Systems, apparatus, and methods for fabricating passive identification tags are provided. A method for fabricating a passive identification tag can include: determining a pattern for a resonant structure of a resonance layer of the passive identification tag, and/or determining a pattern for a dielectric structure of a characteristic layer to be disposed on the resonance layer. The method can further include: generating, based on the pattern for the resonant structure, the resonant structure on a substrate to form the resonance layer. The resonant structure generated by the method can respond to an incoming detection signal by transmitting or reflecting a tag response. The method can further include: generating, based on the pattern for the dielectric structure, the dielectric structure on the resonance layer to form the characteristic layer. The dielectric structure can modify the tag response, so that a modified tag response is transmitted or reflected to a receiver.

Abstract: One variation of a method includes: accessing a target tag identifier for an identification tag; deriving a set of target radio frequency signal characteristics that encode the target tag identifier; and transforming the set of target radio frequency signal characteristics into a map of volumes of a dielectric material arranged proximal a target resonator within the identification tag to modulate a baseline response signal of the target resonator to passively broadcast a target response signal exhibiting the set of target radio frequency signal characteristics. This variation of the method further includes generating a print file according to the map. This variation of the method also includes, at a printer: accessing the print file; loading the identification tag including a substrate and the target resonator; and fabricating volumes of the dielectric material, proximal the target resonator, according to the print file.

Abstract: System, device, and method for detecting a passive identification tag and identifying a tag ID for the passive identification tag are provided. The system can include a transmitting system, a passive identification tag, and a receiving system. The transmitting system generates one or more detection signals to interrogate the passive identification tag, where the one or more detection signals includes a first detection signal having a first frequency range. The passive identification tag receives the one or more detection signals, and generates at least a first tag response in response to the first detection signal. The receiving system receives the first tag response, and processes the first tag response to determine a plurality of signal components for the first frequency range, where the plurality of signal components can be used to determine the tag ID.
