Abstract
One embodiment is directed to a tray for use in a subrack of a rack, the tray comprising a printed circuit board configured so that a plurality of connections can be made at a plurality of positions on the printed circuit board. Each of the plurality of connections involves at least one connector having an RFID tag associated therewith. The tray further comprises a plurality of RFID antennas integrated into the printed circuit board, each the RFID antennas associated with a respective one of the positions. The printed circuit board is configured to localize a field emitted from each RFID antenna so that only the RFID tag associated with that RFID antenna is energized and read.
