More Information
Summary:The present subject matter provides an RFID device that operates in wide-band and is orientation insensitive. The RFID device includes a first resonator and a second resonator. The first resonator includes a sheet of electrically conductive material, defining an area covered by a perimeter. The RFID device also includes a slot defined by opposing sides and the slot being extended from an open end of an edge of the perimeter of the sheet to a closed end stretching within an internal region of the sheet. The RFID device includes a conductive member placed between the open end and closed end and is contoured by the slot in between. The second resonator includes a loop conductor coupled to an integrated circuit (chip). The second resonator is contained within the closed end of the slot and is spaced by a gap from the opposing sides. The RFID device is formed on a substrate.
