Abstract
A radio frequency identification tag (14) utilizes an antenna (22) formed in association with, and thus integral to, an article, package, package container, label and/or identification badge (10). In a preferred embodiment, a radio frequency identification tag circuit chip assembly (12) is secured to the article (10) and is electrically coupled to the antenna (22) formed on the article (10). Printing a conductive pattern on the article using conductive ink forms a preferred antenna.
Claims35
An antenna arranged for use with an electrostatic radio frequency identification (RFID) tag, the antenna comprising:
- a first substrate;
- and
- a conductive pattern formed on the first substrate, the conductive pattern including a first antenna element having a first coupling region and a second antenna element having a second coupling region, the first antenna element isolated from the second antenna element by a non-conductive region disposed in the conductive pattern.
A package container arranged for use with an electrostatic radio frequency identification tag, the package container comprising:
- a package medium, and
- a conductive pattern formed on the package medium, the conductive pattern including a first antenna element having a first coupling region and a second antenna element having a second coupling region, and the package medium having a locally compressed region about the first coupling region and the second coupling region.
An electrostatic radio frequency identification (RFID) tag comprising a first substrate formed to include a recess in a surface thereof and an antenna formed on the surface, the antenna extending into the recess and contacting side walls thereof, and a RFID chip assembly secured within the recess and electrically coupled to the antenna.
A radio frequency identification tag comprising a substrate formed to include a recess in a surface thereof and an antenna formed on the surface, a radio frequency identification tag circuit chip secured within the recess and electrically coupled to the antenna, and a cover secured over the surface, the cover formed to include a cover recess, and the cover recess arranged to register with the recess.
A radio frequency identification tag comprising a substrate having an antenna formed on a surface thereof, a radio frequency identification tag circuit chip secured to the surface and electrically coupled to the antenna, and a cover secured over the surface, the cover formed to include a cover recess, and the cover recess arranged to surround the radio frequency identification tag circuit chip.
