RF and microwave radiation directing or controlling components are provided that may be monolithic, that may be formed from a plurality of electrodeposition operations andor from a plurality of deposited layers of material, that may include switches, inductors, antennae, transmission lines, filters, andor other active or passive components. The conveyor module includes a conveyor surface for transporting sheet material along the feed path and a pneumatic system for developing a pressure differential across the conveyor surface to hold the sheet material on the conveyor surface during transport. The bracket has a heat-radiating portion which is thermally connected to the heat-generating portion. The closed-loop broadband antenna circuit and the feed-point connections may be grounded by a separate path within the device.
