Abstract:
1. A drum-style slip-ring module, comprising: a plurality of stacked electrically-conductive rings; a plurality of dielectric layers electrically isolating the conductive rings, wherein each of the dielectric layers includes a centrally-located aperture; and a cylindrical ground plane positioned in the centrally-located aperture, wherein the module is configured to provide electrical connector to each of the rings at an exterior surface of the module, wherein each of the rings is coupled to a buried feed line that is coupled to the exterior surface of the module by a feed line via for connection to an external device, and wherein the rings are grouped into a first ring group and a second ring group each including at least two of the rings, and wherein the module further comprises: a shield layer coupled between the first ring group and the second ring group, wherein the shield layer is electrically coupled to the cylindrical ground plane.
