Abstract

Abstract An improved waveguide window (10) for use in high power waveguide applications. The window (10) preferably includes a thin sheet (12) of dielectric material having a first planar face (14), a second (16) face, and a support structure (18) attached to the first face (14) to provide mechanical support for the sheet (12). The support structure (18) preferably includes a plurality of parallel conductive support bars (20), each bar having an inner portion (22) attached to the first face (14) and an outer portion (24) extending away from the sheet (12), the outer portion (24) being tapered to minimize wave reflection. At least one bar (20) also has a channel (28) bored therethrough to allow a coolant to flow through the bar (20) to remove heat generated within the dielectric sheet (12). Together, the sheet (12) and the support structure (18) form a waveguide window (10) which may be used to environmentally separate one waveguide section (32) from another (34). The waveguide window (10) preserves the particular environments of each section (32, 34) while allowing electromagnetic waves to propagate through window (10).

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 62 words
A window for placement across an open section of a waveguide, comprising: a sheet of dielectric material having a firsts planar face; and a conductive support structure attached to said first planar face, said support structure forming a thermal and mechanical bond with said planar face to provide mechanical support for, and to conduct heat away from, said sheet of dielectric material.
Claim 2
Dependent Claim 42 words
A window as claimed in claim 1 wherein said support structure comprises a plurality of substantially parallel conductive support bars, each support bar having a first portion attached to said first face, and a second portion extending away from said first face.
Claim 3
Dependent Claim 84 words
A window for placement across an open section of a waveguide comprising a sheet of dielectric material having a first planar face and a conductive support structure attached to said first planar face for providing mechanical support for said sheet of dielectric material, said support structure comprising a plurality of conductive support bars, each support bar having a first portion attached to said first face, and a second portion extending away from said first face, each support bar passing through a selected central point.
Claim 4
Dependent Claim 34 words
A window as claimed in claim 2 or claim 3 wherein the second portion of at least one of said support bars is tapered to form an edge extending away from said first face.
Claim 5
Dependent Claim 24 words
A window as claimed in any one of claims 2 to 4 wherein at least one of said support bars comprises an inner channel.
Claim 6
Dependent Claim 23 words
A window as claimed in any one of claims 1 to 5 wherein said sheet has a thickness between 0.025 and 0.125 cm.
Claim 7
Dependent Claim 78 words
A waveguide assembly comprising a window as claimed in any one of the preceding claims comprising a first waveguide section having a first open end placed around said support structure and against the first face of said dielectric sheet to allow said window to cover said first open end; and a second waveguide section having a second open end placed against the second face of said dielectric sheet to allow said window to cover said second open end.
Claim 8
Dependent Claim 25 words
An assembly as claimed in claim 7 wherein said support bars are separated from each other by a distance of approximately a free space wavelength.
