A recently granted patent (Publication Number: US11861443B2) discloses a method for manufacturing a tag for RFID tracking of fabric, specifically for identifying garments. The tag includes a radio module with ultra-high-frequency transmission, an RFID integrated circuit, an antenna, and a substrate supporting these components. The method involves mounting the radio module and RFID integrated circuit on the substrate, connecting them with metal tracks, mounting the antenna around them, and applying a protective coating to safeguard the electrical and structural interconnections. The protective coating process involves coating the metal tracks and fixing the components to the substrate simultaneously using resin or glue.

Furthermore, the method includes additional steps such as coating a portion of the antenna to protect its connection with the substrate, total incorporation of the RFID integrated circuit and radio module in the protective coating, and solidifying the resin or glue to create a rigid protective layer. The antenna, typically a wire, is stitched onto the substrate at a specific distance from the RFID integrated circuit and radio module to facilitate inductive coupling. The tag, suitable for fabric applications like garment identification in laundry, is manufactured using this method, ensuring direct contact of the protective coating with the components and the immediate substrate area without extending over other regions. The innovative method offers a practical and efficient way to produce RFID tracking tags for fabric, particularly garments, with enhanced durability and performance.
