Abstract

A flexible low-loss dielectric waveguide is made from a flexible low-dielectric constant hollow cylinder filled with high-dielectric constant powder. Alternatively, a rigid or semi-rigid waveguide comprises a groove formed in a low-dielectric constant substrate filled with high-dielectric constant powder.

Independent Claims | See all claims (18)

1. 1. A low-loss dielectric waveguide for replacing conventional electrical metallic waveguides and integrated circuits, comprising:(a) a waveguide housing made from a section of flexible low dielectric constant tubing which is operable to readily be bent to conform to any of various desired electrical waveguide and integrated circuit component shapes;(b) the interior of said section of flexible low dielectric constant tubing being entirely filled with a loose powder having low-loss and a high dielectric constant to provide a purely powdered waveguide core therein which conforms to the interior configuration of said flexible tubing;(c) a very low dielectric constant sealing means provided at opposite ends of said section of flexible low dielectric constant tubing for retaining said low-loss, high dielectric constant powder within said section of flexible low dielectric constant tubing and preventing spilling of said low-loss, high dielectric constant powder; wherein said waveguide can be bent to physically conform to the shape of various electrical waveguide and integrated circuit components as desired.
2. 8. A low-loss dielectric waveguide for replacing conventional electrical metallic waveguides and integrated circuits, comprising:(a) a housing consisting of a substrate of low dielectric constant material having at least one groove formed therein of desired electrical waveguide circuit configuration;(b) the interior of said at least one groove being entirely filled with a loose powder consisting solely of a low-loss and high dielectric constant homogeneous material to provide a purely powdered core therein;(c) means for retaining said high dielectric constant powder within said at least one low dielectric constant housing groove and for preventing spilling of said high dielectric constant powder therefrom;(d) means for waveguide coupling said powdered core into an electrical circuit.
