Compact waveguide filter and method

In an electromagnetic energy waveguide filter having a plurality of serially disposed VSWR waveguide elements, a method of reducing the axial length of the filter comprising the step of replacing at least one of said plurality of VSWR waveguide elements with a media transition.

In a waveguide including a waveguide bend and a multiple VSWR element waveguide filter, the improvement wherein said bend is an element of said VSWR filter.

In a waveguide including a media transition and a multiple VSWR element waveguide filter, the improvement wherein said media transition is an element of said VSWR filter.

In a filter adapted for multiple VSWR waveguide elements for passing electromagnetic energy of predetermined frequencies and having at least one VSWR waveguide element, the improvement additionally comprising a waveguide bend for passing electromagnetic energy of said predetermined frequencies.

In a filter adapted for multiple VSWR waveguide elements for passing electromagnetic energy of predetermined frequencies and having at least one VSWR waveguide element, the improvement additionally comprising a media transition for passing electromagnetic energy of said predetermined frequencies.

In a multiple VSWR waveguide element filter that includes one media transition, the improvement wherein said media transition is used as one of said multiple VSWR elements.
