ELECTROTEXTILE RFID ANTENNA

摘要

A system for reading transponders may include a printed circuit board and an electrotextile antenna. The printed circuit board may include an RFID reading circuit, and the electrotextile antenna may be electrically connected to the printed circuit board via a connection. The electrotextile antenna may be composed of a material made by blending or coating textiles with a metal, and the electrotextile antenna may be configured to transmit and receive signals between the RFID reading circuit and RFID tags.

主权项

1. An apparatus comprising:
an electrotextile antenna that communicates with radio frequency identification (RFID) transponders, the electrotextile antenna comprising a conductive fabric including at least two different metals and that has a conductivity of between 1.0×105 Siemens/meter and 5.0×105 Siemens/meter, wherein the electrotextile antenna comprises conductive elements, wherein the conductive elements comprise:
two or more spatially separated conductive cell patches capactively coupled together;a feed pad; andone or more conductive feed lines connected to the feed pad, and wherein the one or more conductive feed lines are electrically coupled with the one or more conductive cell patches, creating a radiative pattern for reading RFID transponders in a corresponding interrogation zone.
