Abstract
A electrical structure and associated method for collimating a wireless signal between a RFID transceiver and a RFID tag. The electrical structure comprises a RFID tag and an enclosure structure. The enclosure structure comprises a radio frequency opaque material. The RFID tag is located within the enclosure structure. The enclosure structure is adapted to collimate, a first radio frequency signal from the RFID transceiver to the RFID tag.
Claims23
An electrical structure comprising:
- a RFID tag;
- and
- an enclosure structure comprising a radio frequency opaque material, wherein the RFID tag is located within the enclosure structure, and wherein the enclosure structure is adapted to collimate, a first radio frequency signal from a first RFID transceiver to the RFID tag.
An electrical structure comprising:
- a first RFID transceiver;
- and
- an enclosure structure comprising a radio frequency opaque material, wherein the RFID transceiver is located within the enclosure structure, and wherein the enclosure structure is adapted to collimate, a first radio frequency signal from the first RFID transceiver to a first RFID tag.
A system comprising:
- a RFID tag;
- a first RFID transceiver within a first enclosure structure, wherein the first enclosure structure comprises a first radio frequency opaque material;
- and
- a second RFID transceiver within a second enclosure structure, wherein the second enclosure structure comprises a second radio frequency opaque material, wherein the first enclosure structure is adapted to collimate a first radio frequency signal comprising a first frequency from the first RFID transceiver to the RFID tag, and wherein the second enclosure structure is adapted to collimate a second radio frequency signal comprising a second frequency from the RFID tag to the second RFID transceiver in response to the first radio frequency signal.
