Abstract
A dielectric wave guide cable (1) includes a tubular core (2) made from a low loss material having a certain permittivity. The tubular core (2) is encompassed by a cladding (3) having, compared to the tubular core (2), a lower permittivity. The tubular core (2) may be coated on the inside by a coating (3) having a higher permittivity. The cladding (3) may be encompassed by a jacket (4).
Claims15
A dielectric wave guide cable (1), adapted for a frequency range of 110 to 140 GHZ, comprising:
- a tubular core (2) made from a first material having a first permittivity, encompassed by a cladding (4) having, compared to the tubular core (2), a second permittivity which is lower than the first permittivity wherein the tubular core (2) comprises on an inside wall thereof, an inner layer (3) having a third permittivity which is higher than the first permittivity, wherein the inner layer (3) comprises a coating providing a bandgap structure for field confinement within the tubular core.
