ABSTRACT:
Processes and apparatus for manufacturing radio frequency transponders having substrates formed from a flexible tape or film are disclosed. The RF transponders are formed on the tape so that their longest dimension (e.g., their length ("L")) is oriented parallel to the length of the tape. This layout places few or no constraints in the transponder's length allowing the length of the transponder's antenna circuit to be adjusted to satisfy the requirements of various applications.
