Abstract
A fixture for a miniature thin-profile RFID proximity transponder has cap and a planar base, both produced from thin flexible plastic sheet stock. The cap is formed with an inset center that is bounded by a relatively planar, relatively floppy brim that is bounded by a spaced outer edge. The inset center is shaped and inset to define an open cavity to closely accommodate the transponder. The planar base is about the same size as a planar surface containing the cap'"'"'s outer edge for closing the open cavity. An ultrasonically welded seam is utilized to join the cap'"'"'s brim to a matching portion of the base in order to form thereby a relatively floppy brim composite with the transponder is situated in the closed cavity in a close fit. Adhesive on the base'"'"'s exterior side allows adhesive attachment of the combination fixture and transponder to another article.
