Abstract
A method and apparatus for manufacturing thin RFID tags adapted to be mounted proximate an interfering substance, such as metal or liquid. Each tag comprises: a web substrate having a predetermined thickness; an antenna attached to the substrate; and an RFID integrated circuit connected to the antenna, the RFID integrated circuit comprising a tank circuit adapted to be tuned in response to an RF signal after the tag has been mounted proximate the interfering substance. In one embodiment, the tag is manufactured using roll-to-roll manufacturing technology.
Claims21
An RFID tag adapted so as to be mountable proximate an interfering substance, the tag comprising:
- a substrate having a predetermined thickness;
- an antenna mounted on the substrate;
- and
- an RFID integrated circuit connected to the antenna, the RFID integrated circuit comprising a tank circuit adapted to be tuned in response to an RF signal after the tag has been mounted proximate the interfering substance.
An RFID system for use in an RFID application, the system comprising:
- an RFID tag adapted so as to be mountable proximate an interfering substance, the tag comprising:
- a substrate having a predetermined thickness;
- an antenna mounted on the substrate;
- and
- an RFID integrated circuit connected to the antenna, the RFID integrated circuit comprising a tank circuit adapted to be tuned in response to an RF signal after the tag has been mounted proximate the interfering substance;
- and
- an RFID reader adapted selectively to broadcast to the tag an RF signal.
A method for manufacturing an RFID tag and mounting the tag proximate an interfering substance, the method comprising the steps of:
- (1) attaching an antenna on a web substrate having a predetermined thickness;
- (2) attaching an RFID integrated circuit, comprising a tank circuit adapted to be tuned in response to an RF signal, on said substrate;
- (3) connecting said antenna to said RFID integrated circuit;
- (4) converting the tag;
- (5) separating the tag from the web;
- (6) mounting said tag proximate the interfering substance;
- and
- (7) tuning the tank circuit using an RF signal.
