摘要
The present invention provides a dielectric waveguide for transmission of millimeter-wave signals and a cable comprising the same, the dielectric waveguide comprising: an inner core having a dielectric medium adapted to transmit a millimeter-wave signal by carrying an electromagnetic field along the dielectric waveguide, the dielectric medium comprising a dielectric material having dielectric properties adapted to confine the propagating electromagnetic field to the inner core while adding low transmission loss at signal frequencies in a millimeter-wave frequency range. The dielectric medium may be provided as a core of solid dielectric material, one or more bundles of fibers that extend along the length of the inner core, or as granulate of dielectric material that fills the volume of the inner core. The dielectric material may be quartz or alumina.
