Abstract
Abstract A junction for connecting together two waveguides whose major transverse axes are inclined to one another, composed of elements connecting the frontal faces of the waveguides in such a manner that their major axes are adjustably inclined to one another, flanges covering the nonoverlapping frontal faces of the two waveguides, and reactance components disposed at the point of discontinuity produced by the angular offset between the waveguides for compensating for such discontinuity over a broad frequency band.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
A junction for connecting together two waveguides whose major transverse axes are inclined to one another, comprising: means connecting the frontal faces of said waveguides in such a manner that their major axes are adjustably inclined to one another; two flat flanges each connected to a respective waveguide and having flat faces coextensive over their entire extent with a common connecting plane at which said faces directly abut and which cover the nonoverlapping frontal faces of said two waveguides; and inductive and capacitive reactance means disposed at the point of discontinuity produced by the angular offset between said waveguides for compensating for such discontinuity over a broad frequency band.
Claim 2
Dependent Claim
109 words
A junction for connecting together two waveguides whose major transverse axes are inclined to one another, comprising: means connecting the frontal faces of said waveguides in such a manner that their major axes are adjustably inclined to one another; two flat flanges each connected to a respective waveguide and having flat faces coextensive over their entire extent with a common connecting plane at which said faces directly abut and which cover the nonoverlapping frontal faces of said two waveguides; and inductive and capacitive reactance means disposed at the point of discontinuity produced by the angular offset between said waveguides for compensating for such discontinuity over a broad frequency band.
Claim 3
Dependent Claim
27 words
An arrangement as defined in claim 1 wherein the major axes of said waveguides to be connected are inclined at an angle of 45° with one another.
Claim 4
Dependent Claim
17 words
An arrangement as defined in claim 1 wherein each of said waveguides has a rectangular cross section.
Claim 5
Dependent Claim
17 words
An arrangement as defined in claim 1 wherein each of said waveguides has an elliptical cross section.
Claim 6
Dependent Claim
21 words
An arrangement as defined in claim 1 wherein said flanges are circular flanges meeting at the connecting plane between said waveguides.
Claim 7
Dependent Claim
18 words
An arrangement as defined in claim 1 wherein one of said waveguides serves as an antenna feeder line.
