1. A waveguide antenna assembly for transceiving signals of a predetermined radio frequency range to and from an electronic device supported thereby, comprising:
a first conductive layer configured in a conformable loop, wherein the first conductive layer has an inner surface and an outer surface, the inner surface and outer surface having an area coextensively disposed between an outer edge and an opposing inner edge; a second conductive layer configured in a conformable loop, having of an area coextensively disposed between an outer edge and an opposing inner edge, wherein the second conductive layer is collaterally aligned with the inner surface of the first conductive layer so as to electrically isolate the second conductive layer from the first conductive layer for support of waveguide modes corresponding to the signals of the predetermined frequency range; an electrically isolating channel extending between the inner surface of the first conductive layer and the second conductive layer, wherein the electrically isolating channel is dimensionally configured for transmission of the waveguide modes corresponding to the signals of the predetermined frequency range; an aperture for electromagnetically transceiving the signals of a predetermined radio frequency range, wherein the aperture is oriented along a surface of the electrically isolating channel such that the aperture is disposed between the outer edge of the inner surface of the first conductive layer and the second conductive layer; a back short spaced back from the aperture a predetermined distance equal to a resonant length of the waveguide mode wavelength, wherein the back short provides a circuit impedance between the first conductive layer and the second conductive layer for tuning the waveguide for transceiving the signals of a predetermined frequency range; at least one excitation point coupled to the aperture, wherein the at least one excitation point couples the signals of a predetermined frequency range so as to propagate the waveguide modes within the electrically isolating channel; and an electrical feed of the signals of a predetermined frequency range to and from an electronic device. |
