Apparatus and method for assembly, retention and physical protection of radio frequency identification tags for oil drill strings
First Claim
1. An apparatus for retention and protection of a radio frequency identification tag in a recess having a bottom in an oil drill string, comprising:
- a tag housing press fit into the recess in the oil drill string;
said tag housing having a proximal surface and a distal surface wherein said distal surface is adjacent the bottom of the recess;
a tag electronic circuit positioned adjacent said distal surface of said tag housing;
a tag antenna positioned adjacent said proximal surface of said tag housing;
at least one antenna lead extending from said tag electronic circuit to said tag antenna;
a plug of protective material positioned adjacent said proximal surface of said tag housing covering said tag housing and said tag antenna.

Abstract
Various means of identifying individual joints of drill pipe or other drill tools have been suggested but have found only narrow utility. Such means include low frequency radio frequency identification systems that are inherently limited by short read ranges and require the reader antenna be placed directly over and very close to an embedded identification tag. With the development of mid-frequency and high frequency systems for radio frequency identification, read distances become much longer and a Gigahertz identification tag has recently been specifically developed for automatic drill string component identification. This invention provides a means for configuring, assembling and providing in-hole protection to a Gigahertz or other radio frequency identification tags.
