Publication number: 20110267254Abstract: An RFID transponder antenna has a carrier substrate and an auxiliary substrate. The carrier substrate is provided with a contact point for a first connection to an integrated circuit, and a first conductor path including at least two coil turns. A first end of the path forms a contact terminal for a second connection to the integrated circuit. The other end forms a connection point for an electrical connection to a second conductor path. The second path on the auxiliary substrate forms a bridge over the coil turns. The second conductor path has one end connected to the contact point, and another end connected to the connection point providing a permanent connection between the auxiliary substrate and/or the first conductor path, and the carrier substrate and/or second conductor path; the permanent connection being formed at least at one point lying between both ends of the auxiliary substrate.Type: ApplicationFiled: September 25, 2009Publication date: November 3, 2011Applicant: KSW MICROTEC AGInventors: Robert Semar, Michael Schaefer, Marco Wagner, Henry Prescher

Publication number: 20110062236Abstract: A magnetic-guiding laminate is used to improve wireless communication between a transmitter and a receptor disposed on a substrate, regardless of the substrate materials. The laminate can comprise one or more layers of magnetic or non-magnetic material with different magnetic property. For example, the laminate can comprise a paramagnetic layer disposed on a diamagnetic layer, where the paramagnetic layer attracts the magnetic field toward the RFID antenna, and the diamagnetic layer prevents the magnetic field from dispersing in the substrate. Alternatively, the laminate can comprise multiple paramagnetic layers, wherein at least two layers have different magnetic properties, such as different permeability values.Type: ApplicationFiled: September 15, 2010Publication date: March 17, 2011Applicant: KSW MICROTEC AGInventors: Frank Kriebel, Carsten Nieland, Hannes Küllig

Patent number: 7768459Abstract: A transponder card comprises a carrier substrate arranged without interlayers between two protective plastic plates, a planar frame antenna, on the substrate with two supply connections and a conductor track connecting the supply connections, and an integrated circuit with two antenna connections. The antenna connections are electrically connected to the two supply connections and the integrated circuit is arranged such that the conductor track does not run through between the antenna connections. The conductor track may include at least two first conductor track segments and at least one second conductor track segment. Each end of the second conductor track segment is electrically connected to a respective first conductor track segment. The second conductor track segment crosses at least one of the two first conductor track segments at least once and is electrically insulated from the first conductor track segment by at least one nonconductive separation element.Type: GrantFiled: May 28, 2008Date of Patent: August 3, 2010Assignee: KSW Microtec AGInventor: Thomas Reppe

Publication number: 20080297421Abstract: A radio frequency device comprises a radio frequency transponder having a radio frequency circuit and a radio frequency antenna, and a sensor conductively connected to the radio frequency antenna so that a measurement can be retrieved from the sensor by communicating with the transponder. The radio frequency antenna comprises a first portion which is used primarily for receiving and/or sending of radio frequency signals, and a second portion which is used primarily for conductively connecting the sensor to the first portion of the radio frequency antenna and which enables placing the sensor in a spaced-apart spatial relation to the first portion of the radio frequency antenna.Type: ApplicationFiled: May 29, 2008Publication date: December 4, 2008Applicant: KSW Microtec AGInventors: Frank KRIEBEL, Robert SEMAR
