Patent ID: 8496184

Claim:
A tagging transponder device comprising: a surface acoustic wave (SAW) piezoelectric device bonded directly onto a bottom surface of an antenna substrate by a first bonding agent configured to maintain the bond within a temperature range of −67° F. to 662° F.; a dome enclosure positioned over the SAW piezoelectric device, the dome enclosure having a bottom dome edge hermetically sealed with a second bonding agent to the bottom surface of the antenna substrate such that the SAW piezoelectric device is hermetically encased within the dome enclosure and the bottom surface of the antenna substrate, the second bonding agent configured to maintain the hermetic seal between the bottom dome edge and the bottom surface over the temperature range of −67° F. to 662° F.; a predetermined gas being about the SAW piezoelectric device, the predetermined gas being hermetically encased within the dome enclosure and the bottom surface of the antenna substrate, the predetermined gas being selected from a group consisting of helium, nitrogen and other gases comprising similar minimal expansion characteristics over the temperature range of −67° F. to 662° F.; an antenna layer covering a substantial portion of a top surface of the antenna substrate; an electrical connection extending from the SAW piezoelectric device, through a via in the antenna substrate and to a portion of the antenna layer, wherein the via is hermetically sealed with a sealing compound such that the gas does not escape from about the SAW piezoelectric device; and an outer radio frequency transparent potting material substantially covering the top surface and the bottom surface of antenna substrate as well as the dome enclosure and the antenna layer.
