Abstract
A miniature radio-frequency identification (RFID) transceiver and a method for making the same are provided. The RFID transceiver is small in size and physically rugged. The RFID transceiver includes an integrated circuit and a radio-frequency antenna that is fixed to the integrated circuit and electrically connected to the integrated circuit. The integrated circuit includes an RFID transceiver circuit. The antenna may be a single thin-film layer over the top surface of the integrated circuit or multiple layers that form a larger antenna in a compact, folded structure. Multiple antenna layers may also be used to form a three-dimensional structure for improved antenna operation or may be used to form separate, independent antennas.
