Abstract
Gas cylinder and RFID (radio frequency identification) transponder assemblies and related methods are disclosed that utilize fixed orientations for RFID transponders to overcome problems existing with previous solutions. The disclosed embodiments provide an advantageous solution for utilizing metal plates, such as metal identification plates, to house RFID transponders and to fix the orientation of the RFID transponders to overcame the adverse effects of metal structures distorting the magnetic fields associated with gas cylinders. This fixed orientation combined with a transponder embodying a copper wire antenna wound around a longitudinal axis of a ferrite core and the use of PSK (phase shift keying) modulation allows for adequate reader performance despite the presence of interfering metal structures such as a metal plate used to house an RFID transponder.
