Embroidered Antenna-Microchip Interconnections and Contour Antennas in Passive UHF RFID Textile Tags

We studied the possibilities of embroidered antenna-IC interconnections and contour antennas in passive ultrahigh-frequency radio-frequency identification textile tags. The tag antennas were patterned from metal-coated fabrics and embroidered with conductive yarn. The wireless performance of the tag...

Zusammenfassung:	We studied the possibilities of embroidered antenna-IC interconnections and contour antennas in passive ultrahigh-frequency radio-frequency identification textile tags. The tag antennas were patterned from metal-coated fabrics and embroidered with conductive yarn. The wireless performance of the tags with embroidered antenna-IC interconnections was evaluated through measurements, and the results were compared to identical tags, where the ICs were attached using regular conductive epoxy. Our results show that the textile tags with embroidered antenna-IC interconnections attained similar performance. In addition, the tags where only the borderlines of the antennas were embroidered showed excellent wireless performance.
