ABSTRACT:
Systems and methods are disclosed for miniature transponders having capsule enclosure housings including a magnetic antenna core, such as a ferrite core, with a shaped form to provide space for an integrated circuit also included within the capsule enclosure housing. In addition, metal wire windings surround the antenna core, and these wires can be direct bonded to connections on the integrated circuit. Further, a stabilizing epoxy or other material can be inserted within the capsule enclosure housing to secure the antenna core and the integrated circuit within the capsule enclosure housing.
