Abstract
A surface wave transmission line enclosed in a dielectric shield and supported within the enclosure at a predetermined distance from the base of the enclosure. The enclosure being constructed such that the surface wave transmission line may be in close proximity to reflecting objects positioned along the enclosure and at a predetermined distance from a mounting structure.
Claims8
A transmission line apparatus comprising:
- a C-shaped channel having an open side and upper and lower sections of unequal length with an interconnecting section therebetween, said upper section of a length greater than said lower section;
- propagation means for guiding signal waves;
- means, constructed of a first dielectric material, for supporting said propagation means adjacent said open side of said C-shaped channel;
- and
- means, constructed of a second dielectric material, and Z-shaped having an upper section, a lower section and an interconnecting section therebetween, positioned in said C-shaped channel with said upper and lower sections thereof adjacent said upper and lower sections of said C-shaped channel respectively for shielding and containing said propagation means and said support means, said upper section extending from said interconnecting section of said Z-shape along said upper section of said C-shaped channel towards the end of said upper section of said C-shaped channel adjacent said open side and said lower section extending from said interconnecting section of said Z-shape, along said lower section of said C-shaped channel towards said interconnecting section of said C-shaped channel.

A transmission line apparatus comprising:
- a C-shaped channel having an open side and upper and lower sections of unequal length extending from said open side with an interconnecting section extending therebetween, said upper section of a length greater than said lower section;
- propagation means for guiding signal waves;
- means, constructed of a first dielectric material, for supporting said propagation means adjacent said open side of said C-shaped channel;
- and
- means, constructed of a second dielectric material for shielding and containing said propagation means and said support means, said shield means having an upper section, a lower section and an interconnecting section therebetween, and positioned in said C-shaped channel with said upper and lower sections thereof adjacent said upper and lower sections of said C-shaped channel respectively and said interconnecting means extending between said upper and lower sections thereof adjacent said open side, said shield means positioned such that the ends thereof are located predetermined distances from said interconnecting section of said C-shaped channel with said upper section of said shields means extending along said upper section of said C-shaped channel from said interconnecting section of said shield means substantially to said interconnecting section of said C-shaped channel and said lower section of said shield means extending along said lower section of said C-shaped channel substantially to said interconnecting section of said C-shaped channel.
