ABSTRACT:
A thin waveguide window having a broad band of operating frequencies is composed of a metallic frame provided with an opening and a leak-tight closure plate of dielectric material. The frame permits a reduction in dimensions of the plate, with the result that any spurious frequencies introduced by the plate are rejected from the operating frequency band. By giving the plate an oblong shape, it is possible to balance its inductive components by means of its capacitive components at the mid-band frequency. A matching transformer formed by the ridges which are more closely spaced in the vicinity of the window than in the remainder of the waveguide permits matching throughout the frequency band.
