Abstract (en)

[origin: EP1970993A1] A "coil-on-a-chip" RFID tag having an rfid integrated circuit and an antenna contemporaneously formed on a substrate. The antenna is a helical multiple layer, multi-turn coil having an axis of revolution oriented at an acute angle, preferably ninety degrees, with respect to the major body plane of the rfid integrated circuit. The coil has a central opening with an annular core of magnetically permeable material. The RFID tag has an increased operating range over known ID tags.
