Abstract
A flexible test cable has a center conductor (), a conductive sleeve () with an effective electrical length equal to an odd quarter wavelength of a frequency of interest, a dielectric spacer () located inside the conductive sleeve () for preventing a portion of the center conductor from electrically coupling to the conductive sleeve, and a dielectric joint () for maintaining a portion of the center conductor in the middle of an end of the conductive sleeve (). The conductive sleeve () can have a variety of cross-sectional shapes. The dielectric spacer () can be formed in a variety of shapes from rigid or compressible dielectric materials. Likewise, the dielectric joint () can be formed in a variety of shapes from rigid or compressible dielectric materials. Using the dielectric joint () to link together multiple conductive sleeves () results in a flexible test cable () with electrical transparency at the frequency of interest.
