Abstract
A combline waveguide filter obtained by additive printing, including several resonators connected to each other by irises. Each resonator includes a cavity with a longitudinal axis, a transverse axis and a vertical axis. Each cavity is delimited in particular by two walls each extending in a plane perpendicular to the longitudinal axis. Each cavity may include a post extending parallel to the vertical axis inside the cavity. The cross-section of the cavities is non-rectangular.
Claims23
Combline waveguide filter obtained by additive printing of metal, comprising at least two resonators connected together by irises,
- each resonator comprising a cavity with a longitudinal axis, a transverse axis and a vertical axis,
- each cavity being delimited in particular by two walls each extending in a plane perpendicular to the longitudinal axis to thereby define a cross section,
- wherein the cross section of said cavities in a plane perpendicular to the longitudinal axis is non-rectangular, and
- wherein each cavity comprises a base perpendicular to the vertical axis and substantially flat and a respective roof above said base, said respective roof being devoid of a planar surface parallel to said base.
