Abstract
Abstract An electrical coaxial line termination having greatly improved voltage standing wave ratio created by inserting a solid rod conductor axially within and connected to one end of a resistor, one end is connected to the inner conductor of the coaxial line. Preferably, the resistor is positioned within a logarithmically tapered horn which is connected to the outer conductor of the coaxial line at one end and is connected to the end of the resistor remote from the connection of the resistor to the inner conductor of the coaxial line.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
A termination for a coaxial transmission line comprising: a horn-shaped outer conductor; resistance means including an elongated hollow ceramic dielectric member mounted coaxially within said outer conductor and having a resistive coating on one surface thereof, said member having an opening in one end thereof; fluid conduit means including a tube projecting into said opening for delivering fluid coolant to the interior of said member, said tube having a smaller cross section than said opening wherein said fluid coolant is exhausted from said dielectric member between said tube and said member; and a conducting rod positioned within said conduit means.
Claim 2
Dependent Claim
100 words
A termination for a coaxial transmission line comprising: a horn-shaped outer conductor; resistance means including an elongated hollow ceramic dielectric member mounted coaxially within said outer conductor and having a resistive coating on one surface thereof, said member having an opening in one end thereof; fluid conduit means including a tube projecting into said opening for delivering fluid coolant to the interior of said member, said tube having a smaller cross section than said opening wherein said fluid coolant is exhausted from said dielectric member between said tube and said member; and a conducting rod positioned within said conduit means.
Claim 3
Dependent Claim
