    Abstract: It is an object of the present invention to provide a capacitor layer forming material which is applicable to printed wiring boards manufactured through a high-temperature processing of 300° C. to 400° C. of a fluorine-contained resin substrate, a liquid crystal polymer and the like, and exhibits no deterioration of the strength after a high-temperature heating. In order to achieve the object, a capacitor layer forming material for a printed wiring board which comprises a first conductive layer used for forming a top electrode, a second conductive layer used for forming a bottom electrode and a dielectric layer between the first and second conductive layers, characterized in that for the second conductive layer, a nickel layer or a nickel alloy layer is employed. The nickel layer or the nickel alloy layer as the second conductive layer preferably has a thickness of 10 micron meter to 100 micron meter. Further, the sol-gel method is suitably employed to form the dielectric layer on the nickel layer or the nickel alloy layer constituting the second conductive layer.

    Abstract: A structural printed wiring board panel includes a multilayer printed wiring board having opposing, outer faces and interlayer interconnects that route RF, power and control signals. Connection areas are formed in or on at least on one face for connecting the interlayer interconnects and any electrical components. A metallic face sheet is secured onto at least one outer face, adding structural rigidity to the multilayer printed wiring board. A metallic face sheet can have apertures positioned to allow access to connection areas. RF components can be carried by a face sheet and operatively connected to connection areas. Antenna elements can be positioned on the same or an opposing face sheet and operatively connected to RF components to form a phased array printed wiring board (PWB) panel.
