A method and apparatus for packaging a Surface Acoustic Wave (SAW) piezoelectric device into a SAW tagging device for use in a harsh environment is provided. An exemplary SAW tagging device comprises a SAW piezoelectric device within a header container. The header container is electrically connected to an antenna system that comprises an antenna substrate, a dielectric disk that may operate as an antenna reflector in combination with a metal base. The antenna system, antenna substrate, dielectric disk and header container are all contained within a cavity in the metal base. The SAW tagging device is completely encased in a chemical, temperature and environmentally resistive and durable material that is transparent to the operating radio frequency of the SAW piezoelectric device contained therein. A grooved sleeve or ring is provided about the SAW tagging device and is compressible or crushable such that the SAW tagging device can be compression fitted into a borehole in an asset or object in need of being tagged. |
