Abstract
RFID tags capable of operating in harsh environments include an RFID chip and antenna positioned on a ceramic substrate are disclosed. Alternatively, in other embodiments an RFID chip may be positioned inside a metal shell and then secured to a work piece in the hazardous environment.
Claims20
A radio frequency apparatus, comprising:
- an RFID chip;
- an antenna coupled to the RFID chip, thereby forming an RFID tag;
- and
- a metal shell coupled to the RFID tag wherein the shell provides a second antenna for the RFID tag.
