Abstract:
1. A communication device, comprising: a coaxial cable having length and first and second ends; the coaxial cable further having a central conductor, a dielectric insulator surrounding the central conductor, and an electric shield conductor surrounding the dielectric insulator; the dielectric insulator serving as a dielectric waveguide having a characteristic impedance Z at an operating frequency range; a termination for electrical energy coupled into or out of the dielectric insulator at approximately the characteristic impedance Z at the operating frequency range to utilize the dielectric insulator as a waveguide for transmission of signals along the length of the coaxial cable; and wherein the central conductor is further used to communicate an electrical signal between the first and second ends; and wherein the termination comprises one or more conductive pads that contact the dielectric insulator of the coaxial cable, wherein energy is passed to or from the one or more conductive pads to provide an interface for use of the coaxial cable's dielectric insulator as a waveguide.
