摘要： A symmetrical two-piece waveguide is described herein. The waveguide comprises an upper structure that forms a first symmetrical portion of at least one channel that defines an energy path between an input portion and a radiator portion of the channel. The waveguide further comprises a lower structure that forms a second symmetrical portion of the channel that is symmetrical to the first symmetrical portion about a separation plane when the upper and lower structures are mated. The upper structure further forms the radiator portion that extends orthogonally from an upper surface of the first symmetrical portion opposite the separation plane. The lower structure further forms the input portion that extends orthogonally from a lower surface of the second symmetrical portion opposite the separation plane. By using symmetry, the disclosed waveguide leverages the benefits of a two-piece design while enabling near-lossless channeling of energy without conductive bonding.

摘要： An antenna assembly includes: an antenna including: a metal signal layer having a radiating surface; and a feed port; and a waveguide surrounding the antenna and configured to guide electromagnetic energy transmitted from the radiating surface in a direction away from the antenna; and a controller module connected to the feed port and configured to drive the antenna to transmit electromagnetic energy from the radiating surface; wherein the antenna, waveguide, and controller module are configured such that, when the controller module drives the antenna, the transmitted electromagnetic energy matches a reception characteristic of an implantable device and is sufficient for the implantable device to create one or more electrical pulses of sufficient amplitude to stimulate neural tissue of a patient, solely using electromagnetic energy received from the antenna, when the implantable device is located at least 10 centimeters away from the antenna.

摘要： A reconfigurable holographic antenna and a method of shaping an antenna beam pattern of a reconfigurable holographic antenna is disclosed. A baseline holographic pattern is driven onto a reconfigurable layer of the reconfigurable holographic antenna while a feed wave excites the reconfigurable layer. An antenna pattern metric representative of a baseline antenna pattern is received. The baseline antenna pattern is generated by the reconfigurable holographic antenna while the baseline holographic pattern is driven onto the reconfigurable layer. A modified holographic pattern is generated in response to the antenna pattern metric. The modified holographic pattern is driven onto the reconfigurable layer of the reconfigurable holographic antenna to generate an improved antenna pattern.

摘要： An assembly for confining electromagnetic radiation in a waveguide. The assembly comprises a waveguide, comprising walls surrounding a cavity and an aperture in the walls that opens to the cavity, and a substrate assembly disposed in the aperture. The substrate assembly comprises a substrate comprising an antenna, wherein the antenna is located within the cavity and is configured for transmission of radiation within the cavity. The substrate assembly comprises an integrated circuit (IC) electrically connected to the substrate, where the IC comprises semi-conductor components and a ground plane on one side of the IC. The ground plane is located between the IC semi-conductor components and the antenna. The ground plane is located across the aperture to reduce the area of the aperture and to reflect some of the radiation directed to the aperture back into the cavity.

摘要： A dual-mode feed network for an antenna array or combination antenna is provided. Two transmission line structures propagate signals according to two different electromagnetic propagation modes, such as TE, TM, TEM and quasi TEM modes. The two transmission line structures are operatively coupled to different components of the antenna array. One transmission line structure may be a stripline or microstrip, and the other transmission line structure may be a waveguide such as a Substrate Integrated Waveguide. Both transmission line structures may branch to reach multiple elements of the antenna array. The transmission lines may share common features, for example by embedding the stripline within the waveguide.

摘要： An antenna feed with mode suppression includes a transition section, having a window for connecting to an output port of a waveguide and having inner and outer conductors forming a coaxial waveguide that couples energy from the waveguide into a horizontal TE11 mode in the coaxial waveguide. A polarizer section is coupled to the transition section and generates circular polarization from the horizontal mode of the transition section. A radiator section is coupled to the polarizer and provides an output signal for the antenna feed. The transition section includes an electrical short coupling the inner and outer conductors. The electrical short is disposed adjacent to the window of the transition section. A dielectric block is also disposed between the inner and outer conductors and adjacent to the electrical short along the axis of the coaxial waveguide. A surface of the dielectric block is coated with a thin film sheet resistance.

摘要： A low complexity/cost beamsteering antenna includes a central line feed affixed to a radial waveguide structure, radiating elements positioned along the circumference of the radial waveguide structure, and a plurality of active elements interspersed along the surface of the radial waveguide structure between the central line feed and the radiating elements. The active elements may comprise PIN diodes or microelectromechanical system (MEMS) components, and may be selectively activated/deactivated by DC switches in order to direct the propagation of an RF signal over the radial waveguide structure in a manner similar to a power divider. As a result, the RF signal may be funneled to selected radiating elements, thereby effectively directionally aiming the main lobe of the emitted radiation pattern to beamsteer the wireless transmission.

摘要： A broadband antenna element for RF transmission and reception over cellular frequencies. The antenna element is formed of conductive material on a substrate surface of conductive material in the form of a pair of half portions extending in opposite directions to distal tips defining the widest distance of a mouth of a cavity. The mouth converges to reduce in cross-section to a narrowest point at a plurality of different flare angles defined by the edges of the two half portions in between the pair of half portions forming the element. The resulting antenna element radiates and receives a wide band cellular frequencies enabling a single element to serve different providers operating on different frequency bands in the cellular spectrum between 680 MHz to 1900 MHz.
