Abstract: A detectable label and associated methods of making a detectable label are provided. One example of the detectable label may include a coil and a capacitor arranged in an LC circuit. The flux direction of the LC circuit is generally parallel a package when the detectable label is attached to the package.

Abstract: Manufacturing antennas for a dual tag by: providing a web structure having a dielectric layer between a first metal layer and a second metal layer; depositing a first resist on the first metal layer to define a radio frequency (RF) coil and a first electrode of an RF capacitor; depositing the first resist on the second metal layer to define a second electrode of the RF capacitor; depositing a second resist on the second metal layer to define connection pads for a near field antenna, wherein one of the first resist and the second resist on the second metal layer defines a far field antenna and the near field antenna; and etching the first and second metal layers to form the RF coil, the electrodes of the RF capacitor, the far field antenna, the near field antenna, and the connection pads.

Abstract: In one embodiment, a method of manufacturing an RFID label includes providing a web structure comprising a dielectric layer and a metal layer; depositing a non-removable resist on the metal layer, the deposition of the non-removable resist defining an antenna; depositing a removable resist on the metal layer, the deposition of the removable resist defining connection pads for connecting an integrated circuit (IC) to the antenna; etching the metal layer to form the antenna and the connection pads; removing the removable resist from the metal layer to expose the connection pads; and attaching the IC to the connection pads.
