Abstract
A micro radio frequency identification tag for use on articles in an equipment identification and tracking system includes a substrate, an RFID chip, a power storage means, an antenna, and a conductive means. The substrate has a pair of surfaces. The RFID chip and power storage means are operatively retained on one surface. The antenna is operatively retained on the other surface of the substrate and acts as a conductive layer. The conductive means extends between the surfaces of the substrate to operatively connect the antenna to the RFID chip and power storage means.

A micro radio frequency identification tag for use on an article in an equipment identification and tracking system, the micro radio frequency identification tag comprising:
- a substrate having a first surface and a second surface, each one of said surfaces including a width and a longitudinal length, said longitudinal length being greater than said width;
- an RFID chip operatively retained on the first surface by an anchor;
- a power storage means, said power storage means comprising at least a pair of capacitors operatively retained on the first surface, said RFID chip being spaced between said capacitors;
- a continuous planar antenna operatively retained on the second surface, said antenna enabling communication between said substrate and said article;
- and
- a conductive means extending between the first surface and the second surface to operatively connect the antenna to the RFID chip and the power storage means.
A method of utilizing a micro radio frequency identification tag with an article in an equipment identification and tracking system, comprising the method steps of:
- 1) providing an RFID tag, said RFID tag including a substrate having a first surface and a second surface, each one of said surfaces including a width and a longitudinal length, said longitudinal length being greater than said width;
- an RFID chip operatively retained on the first surface by an anchor;
- a power storage means, said power storage means comprising at least a pair of capacitors operatively retained on the first surface, said RFID chip being spaced between said capacitors;
- a continuous planar antenna operatively retained on the substrate, said antenna enabling communication between said substrate and said article;
- and a conductive means to operatively connect the antenna to the RFID chip and the power storage means,
- 2) encapsulating at least a portion of said RFID tag with an encapsulant,
- 3) adhering the non-encapsulated conductive layer of the RFID tag to an article to be identified and tracked.
