Hi, Rogers used to make the flat custom capacitors. They still make the busbar products (http://www.rogers-corp.com/nv/busbarindex.htm).

They were made by a company that also made little bus bars that were used to carry power and ground around on two layer boards. I don't remember the manufacturer, but if I do I will let you know.
