An array of electrically conductive waveguides is made a method including defining slots in broad surfaces of planar dielectric slabs. The surfaces of the slabs, including slots, are metallized. The broad sides of the slabs are juxtaposed, with the slots registered with the planar surfaces of another slab, to form one or more closed waveguides. The waveguides may feed microchips, or act as antennas. The slabs may include electrical conductors andor heat pipes. Heat pipes are made by defining apertures with the dielectric slabs, and introducing wick material into the apertures.

Molded or encapsulated transmit-receive module or TR module/antenna element for active array

An encapsulated heat pipe is made by placing a removable elongated solid partially within a mold, filling the mold with a solid dielectric material, and removing the elongated solid from the dielectric material defining an elongated cavity that extends within the solid dielectric material. Next, a wick material is inserted into the periphery of the elongated cavity, then a coolant liquid is inserted into the elongated cavity and the open end of the elongated cavity is sealed.

Method for making an integrated active antenna element

A flexible connection extending between two objects which have relative motion is subject to deleterious electrical performance or damage due to fatigue or resonance. The connection is structurally augmented and therefore stiffened without affecting the range of motion by use of one of a pantograph or a bell-crank-and-carriage stiffener arrangement. The structural augmentation connects to the ends of the connection and also to locations along the length, to force portions of the connection to accept motion proportional to their distance between the moving ends.
