Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a coil design for wireless signal transmission devices where the impedance matching circuit is created wholly or partially by overlapping conductor tracks within the coil itself. This integration removes or reduces the need for discrete matching components like external capacitors, leading to a more flexible, robust, and reliable assembly. The patent also covers a device using such a coil and a method for manufacturing it, mainly targeting efficient signal transmission via electromagnetic waves.

Use CasesContent extracted from patent full text and abstract with AI.

  • Magnetic Resonance Imaging (MRI) equipment using flexible and integrated transmission/receiving coils
  • Wireless communication devices that require compact and robust antenna structures
  • RFID tag readers and transponders with streamlined circuitry
  • Flexible sensors or transmitters integrated into textiles or medical devices
  • Wireless power transfer systems where coil impedance matching is critical

BenefitsContent extracted from patent full text and abstract with AI.

  • Reduces or eliminates external impedance matching components, simplifying assembly and design
  • Enhances flexibility and robustness of the coil, making it suitable for integration into textiles or flexible devices
  • Improves reliability by minimizing solder joints and potential mechanical weak points
  • Allows more compact coil designs beneficial in space-constrained applications
  • Facilitates easier and potentially more cost-effective manufacturing by using printed or flexible circuit technologies

Patent Abstract

The invention relates to a coil in the form of a transmitting and/or receiving coil of a device for wireless signal transmission by means of electromagnetic waves, wherein the coil has an impedance matching circuit for adapting the connection impedance of the coil to an input impedance of a signal transmitting and/or receiving device of the device for wireless signal transmission to be connected to the coil, wherein the impedance matching circuit is formed entirely or at least partially by at least partially overlapping conductor tracks of the coil. The invention also relates to a device for wireless signal transmission by means of electromagnetic waves, comprising a signal transmitting and/or receiving device and a coil connected to the signal transmitting and/or receiving device. The invention further relates to a method for producing such a coil.
