Abstract
A housing part for a measurement device includes a single metal body having an outer circumferential side wall with an upper end and a lower end and an inner disc-shaped base wall located between the upper and lower ends, wherein the side wall and the base wall define two partially enclosed areas, where the base wall comprises a central hole into which a microwave-permeable glass or ceramic window is fused, microwave guides and dielectric matching elements are provided on both sides of the microwave-permeable or ceramic window to propagate microwaves between the desired points such as a radar antenna and radar electronics, and where the matching elements not only adjust the impedance of the microwave window to the impedances of the microwave guides but also put additional compression stress on the surfaces of the fused window, which are preferably ground flat to be flush with those of the center portion.
