  • Publication number: 20150035709
    Abstract: An electronic device includes a sheet shaped antenna which is particularly useful for near field communication. The antenna includes a loop type antenna radiator formed on a carrier, the radiator having spiraling loops along an outer region of the carrier. A first feed terminal is provided at one end of the antenna radiator and disposed inside the loops. A second feed terminal is provided at an opposite end of the antenna radiator and disposed outside the loops. The carrier has a cut-out in proximity to the first feed terminal, which enables the first feed terminal to be bent in the same direction as the second feed terminal without bending an outer segment of the antenna radiator adjacent to the cut-out. In this manner, the feed terminals may be defined on a single layer, allowing for a simplified assembly process.

    Abstract: A method for attaching antennae to RFID tags is disclosed. Included is the use of RFID tags having asymmetrical interconnect system for one or more antennae, such that virtually any rotational orientation of the RFID tag will result in a successful antennae attachment. Two oversized and “L” shaped gold-bumped holes can be arranged on the same side of the ship in an opposing action, such that at least one axis of symmetry is formed. Accordingly, virtually all rotational orientations of the chip are then acceptable when attaching a pair of opposing pole antenna leads. Alternatively, a pair of poles can be located on opposing chips surfaces, such that antenna substrates can be attached to both the top and bottom of the chip to form a product “sandwich”, whereby the rotational orientation of the chip is irrelevant at an antenna attachment step.

  • Patent number: 7230580
    Abstract: An apparatus and method for attaching antennae to RFID tags is disclosed. Included is the use of RFID tags having a symmetrical interconnect system for attaching one or more antennae, such that virtually any rotational orientation of the RFID tag will result in a successful antennae attachment. Two oversized and “L” shaped gold-bumped poles can be arranged on the same side of a chip in an opposing fashion, such that at least one axis of symmetry is formed. Accordingly, virtually all rotational orientations of the chip are then acceptable when attaching a pair of opposing pole antenna leads. Alternatively, a pair of poles can be located on opposing chip surfaces, such that antenna substrates can attach to both the top and bottom of the chip to form a product “sandwich,” whereby the rotational orientation of the chip is irrelevant at an antenna attachment step.
