  • Patent number: 9900058
    Abstract: A near-field identification system having an object that is or contains electrically conductive material and an ultra-high radio-frequency microstrip transponder. The microstrip transponder having a microstrip line and an identification microchip connected to the microstrip line. The microstrip transponder being on the object at a location where the object has an electrically conductive region, the line following at least one edge of the object. When the identification system is being interrogated by an interrogator from below the system an identification signal from the identification microchip is transmittable from the microstrip line via magnetic near field induced by electric current on the edge of the object to below the object. Also discussed is a method for identifying an object or the kind of an object that is or contains electrically conductive material using near-field identification.

  • Publication number: 20150341088
    Abstract: A near-field identification system comprises: i) an object that is or contains electrically conductive material; and ii) an ultra-high radio-frequency microstrip transponder comprising a microstrip line and an identification microchip connected to the microstrip line; and wherein: the microstrip transponder being on the object at a location where the object has an electrically conductive region, the line following at least one edge of the object. The system is configured, when identification system is being interrogated by an interrogator from below of the system, in such a manner that an identification signal from the identification microchip is transmittable from the microstrip line via magnetic near field induced by electric current on the edge of the object to below the object in such a manner that the identification microchip is identifiable.
