Abstract

An RF antenna grid design in which the antenna array is installed on a patch panel cover allows for the retrofitting of an RF antenna grid on existing patch panel based systems without disrupting network operation. An apparatus for determining connectivity between device ports on a patch panel and cable ends having corresponding RFID tags attached thereto comprises a patch panel having a plurality of device ports and a patch panel cover comprising a plurality of RFID antennas, where each of the RFID antennas comprises one or more protruding portions thereof, each of the protruding portions of the RFID antennas being in close physical proximity to one or more of the plurality of device ports when the patch panel cover is positioned in a fixed positional relationship to the patch panel (e.g., when the patch panel cover is “attached” to the patch panel).
