ABSTRACT:
A capacitive coupler for a microwave circuit that has a first cavity and a second cavity separated by a wall. The separating wall has an aperture that, due to its shape, is capacitive. The aperture has a pair of elongated walls separated by a pair of side walls. The elongated walls and the side walls each have a thickness substantially thicker than what is now the industry standard. At least one of the elongated walls has a ridge. Because the distance between the first elongated wall and the second elongated wall is substantially greater than that previously known, the aperture may be easily manufactured.
