Devices and methods are provided for
wireless communication with a target, such as an
optical disc or an electronic device. The devices include an integrated processor and an antenna that are connected to the target, which enable a
wireless communication with an associated reader or scanning
system. The
integrated circuit may be embedded in the target attached to the surface of the target, or in a
label attached to the target. In a similar manner, the antenna may be embedded in the target, attached to the surface of the target, or in a
label attached to the target.
Interconnection lines may be used connect the integrated processor to the antenna, and may include a
feedthrough arrangement for passing electrical signals between the surface and the interior of the target. A demodulator may also be positioned adjacent or on the antenna, allowing a long lead line to pass demodulated data to the
integrated circuit. In one example, the antenna is positioned in or on a case that holds the target, with
lead lines connecting the antenna to the target's
integrated circuit. One, two, or three antennas may be used, with the multi-antenna arrangements preferably arranging the antennas orthogonally.
