Abstract
A radiofrequency transceiver device comprises an electronic circuit including a chip and a first antenna electrically connected to the chip, a textile-core thread formed of a non-conductive material, and a second antenna formed of a textile element in an electrically conducting material and disposed in non-contiguous turns around and along the textile-core thread. The electronic circuit is disposed relative to the second antenna so as to allow the electromagnetic coupling of the first and second antenna. A label may comprise the radiofrequency transceiver device. A particular method may be used to manufacture such a device.
Claims20
A radiofrequency transceiver device, comprising:
- an electronic circuit comprising a chip and a first antenna electrically connected to the chip;
- a textile-core thread comprising a non-conductive material;
- and
- a second antenna comprising a textile element including an electrically conductive material, the second antenna arranged in non-contiguous turns around and along the textile-core thread;
- wherein the electronic circuit is disposed relative to the second antenna to allow electromagnetic coupling of the first antenna and the second antenna.
A method for manufacturing a radiofrequency transceiver device, the method comprising:
- assembling a plurality of electronic circuits on a textile-core thread, so as to space them away from one another along the textile-core thread, the electronic circuits each comprising a chip and a first antenna electrically connected to the chip;
- and
- forming a second antenna comprising a textile element including an electrically conductive material and arranged in non-contiguous turns around the textile-core thread.
