Abstract
Abstract A tuning arrangement for a hermetically sealed strip transmission line is provided. A portion of the ground plane of the strip transmission line is removed leaving a portion of the dielectric substrate exposed. An enclosure surrounds the entire transmission line except for the area thereof where the ground plane is removed and the dielectric is exposed. A tuning stub is supported with respect to the removed area of the ground plane so as to enable tuning of the transmission line by the stub. Since the dielectric substrate remains between the inner area of the enclosure and the outside atmosphere, a seal can be maintained between the inner area of the enclosure and the outside atmosphere.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
In combination, a transmission line circuit arrangement of the type including a dielectric substrate with a broad conductor on one surface of said substrate and at least one narrow striplike conductor on the opposite surface of said substrate, an enclosure surrounding said circuit arrangement and having a wall in fixed contact with said broad conductor, there being an opening through said wall and said broad conductor exposing an area of said dielectric substrate with said substrate isolating the inner area of said enclosure from the outside thereof, and means positioned at said opening which is adjustable relative to said opening for tuning said circuit arrangement.
Claim 2
Dependent Claim
105 words
In combination, a transmission line circuit arrangement of the type including a dielectric substrate with a broad conductor on one surface of said substrate and at least one narrow striplike conductor on the opposite surface of said substrate, an enclosure surrounding said circuit arrangement and having a wall in fixed contact with said broad conductor, there being an opening through said wall and said broad conductor exposing an area of said dielectric substrate with said substrate isolating the inner area of said enclosure from the outside thereof, and means positioned at said opening which is adjustable relative to said opening for tuning said circuit arrangement.
Claim 3
Dependent Claim
134 words
In a strip transmission line circuit assembly of the type where a strip transmission line is positioned within a sealable enclosure, said line being formed of a dielectric substrate having a broad conductor on one surface of said substrate and at least one narrow striplike conductor on the opposite surface of said substrate, the broad conductor being fixed to a wall of said enclosure, the improvement whereby an adjustable tuning means is provided for said assembly comprising the wall and the broad conductor having an opening therethrough to expose an area of said substrate opposite said narrow conductor, the substrate maintaining isolation between the inner area of said enclosure and the outside thereof, and means positioned at said opening which is adjustable relative to said exposed area of said substrate for tuning said assembly.
Claim 4
Dependent Claim
134 words
In a strip transmission line circuit assembly of the type where a strip transmission line is positioned within a sealable enclosure, said line being formed of a dielectric substrate having a broad conductor on one surface of said substrate and at least one narrow striplike conductor on the opposite surface of said substrate, the broad conductor being fixed to a wall of said enclosure, the improvement whereby an adjustable tuning means is provided for said assembly comprising the wall and the broad conductor having an opening therethrough to expose an area of said substrate opposite said narrow conductor, the substrate maintaining isolation between the inner area of said enclosure and the outside thereof, and means positioned at said opening which is adjustable relative to said exposed area of said substrate for tuning said assembly.
Claim 5
Dependent Claim
35 words
In a strip transmission line assembly as claimed in claim 2, said tuning means comprising a tuning stub mounted in a support so as to be adjustable relative to said exposed area of said substrate.
Claim 6
Dependent Claim
28 words
In a strip transmission line assembly as claimed in claim 3, said stub being metallic and threaded for movement within said support toward and away from said substrate.
Claim 7
Dependent Claim
36 words
In a strip transmission line assembly as claimed in claim 4, said substrate having a cavity therein but not therethrough aligned with said stub to permit passage of said stub in and out of said cavity.
Claim 8
Dependent Claim
19 words
In a strip transmission line assembly as claimed in claim 3, said support being mounted to said broad conductor.
