Cable comprising low loss dielectric waveguide and low loss dielectric waveguide for millimeter wave signal transmission

摘要

The present invention provides a dielectric waveguide for millimeter wave signal transmission and a cable including the dielectric waveguide. The dielectric waveguide includes an inner core having a dielectric medium configured to transmit a millimeter wave signal by passing an electromagnetic field along the dielectric waveguide. The dielectric medium comprises a dielectric, the dielectric having dielectric properties configured to confine the propagating electromagnetic field in the inner core, and adds low transmission loss at signal frequencies in the millimeter wave frequency range. The dielectric medium may be provided as a core of solid dielectric, one or more bundles of fibers extending along the length of the inner core, or particles of dielectric filling the volume of the inner core. The dielectric can be quartz or alumina. [Selected figure] Figure 1
