Abstract
A communication device consistent with certain implementations has a coaxial cable having length and first and second ends. The coaxial cable further has a central conductor, a dielectric insulator surrounding the central conductor, and an electric shield conductor surrounding the dielectric insulator. The dielectric insulator serves 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 center conductor is further used to communicate an electrical signal between the first and second ends. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
