Abstract

A broadband signal junction with sum signal absorption for transmitted signals includes a common hollow conductor with a first predefined cross-section and four laterally-disposed side arm hollow conductors with a predefined cross-section. The cross-sections of the side arm hollow conductors can also be selected to be different. Two first opposing side arm hollow conductors of the four side arm hollow conductors extend along a first axis. Two second opposing side arm hollow conductors of the four side arm hollow conductors extend along a second axis. The first and the second axes are disposed orthogonal to one another and lie in the common plane. The broadband signal junction with sum signal absorption is characterized in that the two first side arm hollow conductors end with a hollow conductor absorber.

First claim

What is claimed is:

1. A broadband signal junction with sum signal absorption for transmitting signals, comprising: a common hollow conductor with a first predefined cross-section; and four side arm hollow conductors disposed in a common plane, the four side arm hollow conducts having a predefined cross-section, wherein two first opposing side arm hollow conductors extend along a first axis and two second opposing side arm hollow conductors extend along a second axis, wherein the first and the second axis are disposed orthogonal to one another lying in the common plane, and wherein the common plane runs orthogonally to a main axis of the common hollow conductor, wherein the two first side arm hollow conductors end with a hollow conductor absorber disposed over the respective predefined cross-section of the two first side arm hollow conductors, wherein each hollow conductor absorber of the two first side arm hollow conductors lie along and terminate on the first axis.

2. The broadband signal junction of claim 1 , wherein the first predefined cross-section of the common hollow conductor is a group consisting of rectangular, square, elliptical, and round.

3. The broadband signal junction of claim 1 , wherein the predefined cross-section of the four side arm hollow conductors is a group consisting of rectangular, square, elliptical, and round.

4. The broadband signal junction of claim 3 , wherein the predefined cross-section of at least one of the four side arm hollow conductors is different from the predefined cross-section of another one of the four side arm hollow conductors.

5. The broadband signal junction of claim 1 , wherein the two second side arm hollow conductors are disposed and/or designed collinear.

6. The broadband signal junction of claim 1 , wherein the four side arm hollow conductors are disposed and/or designed offset from the common plane.

7. The broadband signal junction of claim 1 , including a matching structure disposed inside of the junction, wherein the matching structure has a geometry matched to a desired transmission behavior and can have any arbitrary shape.

8. The broadband signal junction of claim 1 , wherein the signals are split or coupled over an entire bandwidth with a phase shift of 180°.
