Abstract
Abstract An arrangement for wide band inductive coupling of a coaxial line to a hollow conductor, by means of a coupling loop having a first leg extending in axial direction from the inner conductor of the coaxial line into the hollow conductor, and a second leg extending transversely from the first leg to the wall of the hollow conductor, with the free end portion of such first leg projecting beyond the second leg into the hollow conductor, at least two adjustable pins being provided for determining the coupling characteristics which pins extend inwardly from the hollow conductor sidewall, one of such pins being disposed opposite the first leg and extending inwardly toward the latter, while a second of such pins is disposed adjacent to but axially spaced from the projecting portion of the first leg.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
An arrangement for wide band inductive coupling of a coaxial line to a hollow conductor, comprising a coupling loop having a first leg extending in axial direction from the inner conductor of the coaxial line into the hollow conductor, and a second leg extending transversely from the first leg to the wall of the hollow conductor, with the end portion of said first leg projecting beyond the second leg into the hollow conductor, and at least two adjustable trimming pins extending inwardly from the hollow conductor sidewall, one of such pins being disposed opposite said first leg and extending inwardly toward the latter, and a second of such pins being disposed adjacent to but axially spaced from the projecting end portion of said first leg.
Claim 2
Dependent Claim
125 words
An arrangement for wide band inductive coupling of a coaxial line to a hollow conductor, comprising a coupling loop having a first leg extending in axial direction from the inner conductor of the coaxial line into the hollow conductor, and a second leg extending transversely from the first leg to the wall of the hollow conductor, with the end portion of said first leg projecting beyond the second leg into the hollow conductor, and at least two adjustable trimming pins extending inwardly from the hollow conductor sidewall, one of such pins being disposed opposite said first leg and extending inwardly toward the latter, and a second of such pins being disposed adjacent to but axially spaced from the projecting end portion of said first leg.
Claim 3
Dependent Claim
29 words
An arrangement according to claim 1, wherein the second adjustable pin extends inwardly from the hollow conductor wall to which the second leg of the coupling loop is connected.
Claim 4
Dependent Claim
31 words
An arrangement according to claim 1, wherein the space defined by the respective legs of the coupling loop and adjacent hollow conductor wall is at least partially filled by a dielectric.
Claim 5
Dependent Claim
24 words
