Patent ID: 10256517

Abstract:
A waveguide antenna assembly conformable to the configuration of a supported device for transceiving signals of a predetermined radio frequency range comprising at least two collaterally aligned conductive layers configured in a conformable loop so as to form an electrically isolating channel dimensionally configured for support of the waveguide modes of the predetermined frequency range, an aperture for electromagnetically transceiving the signals, wherein the aperture extends along a surface of the electrically isolating channel such that the aperture extends between the outer edge of the inner surface of the first conductive layer and the second conductive layer, a back short spaced apart from the aperture a predetermined distance equal to a resonant length of the waveguide mode wavelength so as to provide a circuit impedance between the first conductive layer and the second conductive layer for tuning the waveguide to transceive the signals, excitation points coupled to the aperture to propagate waveguide modes within the electrically isolating channel for transceiving signals, and mode barrier filters longitudinally oriented in the first conductive layer and the second conductive layer to impede coupling between excitation points. A preferred embodiment of the present waveguide antenna strategically orients the mode barrier filters to enhance antenna transceiving and can be used to support switched TEM and H11 waveguide modes.
