Abstract
Disclosed is a microwave window comprising a circular strip mounted in a circular waveguide section connected, on either side, to a rectangular waveguide containing a matching transformer. The diameter of the circular waveguide is smaller than the diagonal of the rectangle. A wall provides for impervious sealing with respect to the exterior between the rectangular waveguide and the circular waveguide section. Each wall is provided with an aperture included in a portion of cross-section common to the rectangular waveguide and to the circular waveguide section. The area of the aperture is smaller than the area of the portion of cross-section. The disclosed device can be applied to wideband power microwave windows with improved mechanical and electrical behavior.
