Patent ID: 7477500

Claim:
A power and signal distribution system extending in an area having a length and width comprising: a first electrically conductive enclosed channel having intersecting branches for extending over the area in a first plane and having walls of a predetermined thickness greater than a skin depth penetration of a desired low cut-off frequency; a second electrically conductive enclosed channel having intersecting branches for extending over the area in a second plane and having walls with the predetermined thickness, wherein the first and second planes are offset vertically and the first and second channels are electrically coupled at one or more locations over their corresponding expanse; one or more cable drops for routing selected cables from within the first and second enclosed channels to devices disposed vertically offset from the first and second enclosed channels; and a conductor electrically coupled from a ground connection of each of the devices and extending to the first or second enclosed channels, wherein the conductor is electrically coupled to a wall of the first or second enclosed channels.
