    摘要: A plurality of battery-operated transceivers encapsulated by lamination to form a sheet of independent transceivers is tested in a two piece fixture that forms an enclosure surrounding each in-sheet transceiver. Each enclosure has an antenna for transmitting a command signal to the transceiver at a known power level and for receiving a reply message from the transceiver containing a power level measurement made by the transceiver. Test methods using the fixture of the present invention are also described. An RFID tag and interrogator may each include a transmitter and a receiver. The tag and interrogator may communicate with each other at different frequency bands and may communicate in accordance with a wireless communication protocol.

    摘要: A method of forming a radio frequency communication apparatus includes providing a substrate provided with an outermost surface. An RFID is adhered at least partially within the substrate, and the RFID includes an antenna and an integrated circuit. The RFID and substrate together form a radio frequency communication apparatus. A method of forming a radio frequency communication apparatus includes providing a substrate with a frontside surface. An opening is formed through the frontside surface and into the substrate. An RFID is inserted within the opening and adhered to the substrate within the opening. The RFID includes an antenna and an integrated circuit to form a radio frequency communication apparatus.

Each enclosure has an antenna for transmitting a command signal to the transceiver at a known power level and for receiving a reply message from the transceiver containing a power level measurement made by the transceiver. Test methods using the fixture of the present invention are also described. Flexible radio frequency identification (RFID) devices are coupled to a roll of flexible material. Each RFID device coupled to the roll is advanced into a wireless communication region. An antenna in the region separately communicates with each of the RFID devices in a manner that isolates the communication from other REID devices counted to the roll outside the region.
