Abstract

A technique for making an RFID tag that includes creating recesses or trenches in an insulated substrate. Conductive traces are created in the trenches so as to create an inductor coil for the RFID tag.

Description

[0001] Cross References to Related Applications [0002] Under 35 U.S.C. 119, this application claims priority to U.S. Provisional Application No. 61 / 170,836, filed April 20, 2009, entitled "Micro RFID Tags," the entire contents of which are hereby incorporated by reference. Background technique [0003] Radio Frequency Identification (RFID) transponders (tags) typically work in conjunction with RFID base stations (RFID readers) for various inventory control, security, and other purposes. Typically, an item with a tag associated therewith, such as a container with a tag on or within it, is placed into a "readout zone" established by the base station. An RFID base station may transmit an interrogation RF signal modulated by a receiving RFID tag. For example, an RFID base station may generate continuous wave (CW) electromagnetic interference at a certain (carrier) frequency, and this interference may be modulated by an RFID tag to correspond to data transmitted back to the base...
