Abstract: An antenna web can include an RFID antenna on a first side of a substrate. An adhesive can be laminated on a second side of the substrate. The antenna web can then be cut into individual segments for use in constructing an RFID label.

Abstract: A RFID-based identification device comprising a first RFID antenna; and a second RFID antenna, wherein the first and second RFID antennas are in a first arrangement, the resonant frequencies of the antennas are away from an interrogation frequency such that no identification information is transferred, and wherein when the first and second RFID antennas are in a second arrangement, the resonant frequency of the identification device shifts such that identification information is transferred.

Abstract: A game can comprise a board with multiple RFID antennas and a game piece with a RFID antenna. When one of the multiple RFID antennas is adjacent to the RFID antenna in the game piece, the response characteristics of these RFID antennas can change so that the position of the game piece can be determined.

Abstract: A method of constructing an RFID unit can include using a protective layer to hold an integrated circuit chip module to a substrate layer with an antenna unit while a conductive adhesive has not yet fully set.

Abstract: A metalized circuit suitable for application as a radio frequency antenna is produced by forming an antenna coil pattern on a flexible substrate. The antenna coil pattern is formed using a conductive ink which is patterned on the substrate. The conductive ink is cured and an electrical-short layer is formed across the coils of the conductive ink pattern. An insulating layer is formed over top of the electrical-short layer, a metal layer electroplated on top of the conductive layer, and then the electrical-short layer is removed. The use of the electrical-short layer during the electroplating allows for the voltage at the different points on the conductive ink layer to be relatively similar, so that a uniform electroplate layer is formed on top of the conductive ink layer. This results in a better quality radio frequency antenna at a reduced cost.

Abstract: An RFID chip can have an RFID circuit having first and second initial bond pads and conductive paths on the RFID chip connecting the first and second bond pads to the different sides of the chip. The conductive paths including a first side connector on a first side of the chip electrically connected to the first bond pad and a second side connector on a second side of the chip connected to the second bond pad. The first and second side connectors can cover at least half of the first and second side length respectively.
