Microwave stripline phase adjuster

阅读：248发布：2023-01-12

专利汇可以提供Microwave stripline phase adjuster专利检索，专利查询，专利分析的服务。并且This specification describes a microwave stripline phase adjuster wherein the phase of an applied signal is changed by continuous substitution of one dielectric material for another along a length of the stripline circuit path. A constant impedance is maintained by a simultaneous change in the width of the circuit path.，下面是Microwave stripline phase adjuster专利的具体信息内容。

2. A constant impedance microwave stripline phase adjuster comprising: a microwave stripline circuit element including upper and lower dielectric sheets physically attached together and enclosed between upper and lower conducting ground planes, said upper dielectric sheet and said upper ground planes beiNg grooved to expose a length of microwave circuit path, said exposed circuit path having a relatively narrow first segment and a relatively wide second segment; a dielectric member in slideable cooperation with said exposed circuit path, said dielectric member having a first segment of dielectric material of relatively high dielectric constant positioned to interact with a portion of said first segment of said circuit path and a second segment of dielectric material of relatively low dielectric constant positioned to interact with the remainder of said first segment and with said second segment of said circuit path; a conductive strip attached to said second segment of said dielectric member parallel to and in slideable electrical contact with said exposed circuit path, said conductive strip having substantially the same width as said second segment of said exposed circuit path so that the width of said remainder of said first segment of said exposed circuit path is effectively the width of said second segment; and a metal ground plane attached to the exterior surface of said dielectric member.

3. A constant impedance microwave stripline phase adjuster comprising: a microwave stripline circuit element including upper and lower dielectric sheets physically attached together and enclosed between upper and lower conducting ground planes, said upper dielectric sheet and said upper ground planes being grooved to expose a segment of microwave circuit path, said exposed circuit path having a relatively narrow first segment and a relatively wide second segment; a dielectric member in slideable cooperation with said exposed segment of circuit path, said dielectric member having a first dielectric segment of relatively high dielectric constant at the end of said dielectric member adjacent to said first segment of said exposed circuit path and having a second dielectric segment of relatively low dielectric constant at the end of said dielectric member adjacent to said second segment of said exposed circuit path; a conductive strip attached to said second segment of said dielectric member parallel to and in slideable electrical contact with said exposed segment of circuit path, said conductive strip having the same width as said second segment of said exposed circuit path; and a metal ground plane attached to the exterior surface of said dielectric member; said dielectric member being slideable from one extreme position where said first segment of said dielectric member is substantially the only portion of said member interacting with said first segment of said exposed circuit path to a second extreme position where said first segment of said exposed circuit path is in electrical contact with said conductive strip over virtually all of the length of said first segment of said exposed circuit path so that both the dielectric constant of said dielectric member adjacent to said first segment of said exposed circuit path and the effective width of said first segment of said exposed circuit path are simultaneously changed as said dielectric member is moved.

4. A constant impedance microwave stripline signal phase adjuster comprising: a stripline circuit element including a sheet of dielectric material having a relatively low dielectric constant, affixed on one side to a first metal ground plane and affixed on the other side with a first, relatively narrow, signal conductor path; a longitudinal slide having first and second faces, said slide being divided transversely into a first segment of relatively high dielectric material and a second segment of dielectric material having the same dielectric characteristic as said sheet of dielectric material; a second relatively wide signal conductor path affixed on said first face of said low dielectric material slide segment; and a second metal ground plane affixed to said second face of said slide; said slide disposed in said stripline circuit element, the first face of said longItudinal slide in slideable electrical contact with said first signal conductor path so that the dielectric constant of the material adjacent to said signal conductor path and the effective width of said signal conductor path are simultaneously changed as said slide is moved in relation to said stripline circuit element.

5. A constant impedance microwave stripline phase adjusting circuit element comprising: a stripline circuit element the upper dielectric sheet and upper ground plane of which are cut away to expose a segment of circuit path, said exposed segment of circuit path having a relatively narrow first segment and a relatively wide second segment; a slideable dielectric member having a first segment with a relatively high dielectric constant and a second segment with a relatively low dielectric constant backed by a metal ground plane, said slide being aligned in said cut away portion of said upper dielectric sheet and said upper ground plane so that the interface between said first and second segments of said slideable member is positioned over said first segment of said circuit path, so that said first segment of said slideable member is over a portion of said first circuit path segment, and so that said second segment of said slideable member is over the remainder of said first circuit path segment and said second circuit path segment; and a conductive strip having width approximately the same as said second circuit path segment, affixed to said second slide segment adjacent to said exposed circuit path segment, parallel to and in electrical contact with said second circuit path segment so that the width of said remainder of said first circuit path segment is effectively the same as the width of said second circuit path segment.

6. Constant impedance microwave stripline phase adjusting apparatus comprising: a first conducting member having upper and lower surfaces; a first dielectric member having upper and lower surfaces, said lower surface adjoining said first conducting member upper surface; a conducting circuit path segment affixed to the upper surface of said first dielectric member, a section of said segment being narrower than the remainder of said segment; a second dielectric member having upper and lower surfaces, said lower surface adjoining the upper surface of said first dielectric member, said second dielectric member having an interior section removed to expose said conducting circuit path segment; a second conducting member having upper and lower surfaces, said lower surface adjoining said second dielectric member upper surface and having an interior section removed coterminal with said removed section of said second dielectric member; a dielectric slide member having upper and lower surfaces and positioned within said removed interior section of said second members, said slide member comprising adjoining segments of high and low dielectric constant, said segment of high dielectric constant positioned adjacent to said narrower section of said circuit path segment and said segment of low dielectric constant positioned adjacent to the remainder of said circuit path segment; a conductive material of width substantially the same as the remainder section of said circuit path segment having upper and lower surfaces, said upper surface affixed to said lower surface of said slide member segment of low dielectric constant and in slideable contact with said circuit path segment so that both the dielectric constant of said slide member adjacent to said narrower section of said circuit path segment and the effective width of said narrower section of said circuit path segment are simultaneously changed as said slide member is moved; and a third conducting member affixed to the upper surface of said dielectric slide member.
