    Abstract: The invention is directed to deployable reflectarray antenna structure. In one embodiment, the deployable reflectarray antenna structure includes a pair of flexible electrical elements, a feed antenna, and a deployment mechanism that employs a plurality of tapes to respectively transition the pair of flexible electrical elements from an undeployed state in which the elements are folded towards a deployed state in which the deployment mechanism and electrical elements cooperate to form a reflectarray and a subreflector of a reflectarray antenna structure. Further, the deployment mechanism also operates to position the reflectarray and subreflector relative to one another and to the feed antenna so as to realize a reflectarray antenna structure.

  • Patent number: 11901629
    Abstract: Deployable reflector system includes a support structure and a reflector surface secured to the support structure. The support structure transition from a compact stowed configuration to a larger deployed configuration to deploy the reflector surface. The reflector surface is comprised of a carbon nanotube (CNT) sheet. The sheet is intricately folded in accordance with a predetermined folding pattern to define a compact folded state. This predetermined folding pattern is configured to permit automatic extension of the CNT sheet from a compact folded state to a fully unfolded state. The unfolding operation occurs when a tension force is applied to at least a portion of the peripheral edge of the CNT sheet. In some scenarios, the support structure can comprise a circumferential hoop.

  • Patent number: 11870154
    Abstract: A circuit has at least one amplifier and a signal routing device such as one or more switches, and an array of antenna elements from which some subset must be enabled and processed at a time. The antenna elements can be grouped in accordance with an organization scheme (e.g., rows, columns) to enable more flexibility in selecting and routing the signals. The system is used to create one or more beams, which can be pointed (steered) to a wide range of directions by means of selecting one or more feed antennas in a switched-feed antenna without including full receive and transmit circuitry (DSP, frequency conversion) for each feed in the array. In this case, minimizing the number of DSP chains is desirable to reduce the cost, power, and complexity of the antenna. The resulting beam(s) can be combined and manipulated to support multiple users, track several targets, increase operational range, increase radar resolution, or data-rate in communications.

  • Patent number: 11791561
    Abstract: A computer assisted method for manufacturing a foldable paraboloid antenna includes election of a two-dimensional radial Origami pattern with triangular cells and election of a paraboloid surface. The Origami pattern is projected from the paraboloid surface focus onto the paraboloid surface to print the Origami pattern on the paraboloid surface, obtaining triangles with curved sides. A pattern with triangles with straight sides on the paraboloid surface is obtained by joining vertices of the projected curved-sided triangles. The method includes scaling and calculating centroids of the triangles, to reduce each triangle referenced on the corresponding centroid and to determine spacing, obtaining a mesh with segments and triangular cells delimited by the segments. The triangular cells have triangles of reflective rigid material. The mesh is flexible, so each segment width is at least the sum of the thicknesses of two adjacent rigid triangles, and periphery cells have a rounded outer edge.

  • Patent number: 9057199
    Abstract: A structural insulated building panel with a moisture barrier seal includes a structural insulated panel, a seal section, a first spline-receiving grove, and a second spline-receiving groove. The seal section is extended from a phenolic resin sheet of the structural insulated panel so that the seal section can be positioned in between multiple structural insulated panels in order to prevent moisture penetration. The seal section is adjacently positioned with the second spline-receiving groove of the initial structural insulated panel and extends into the first spline-receiving groove of the adjacent structural insulated panel during the installation of multiple structural insulated panels.

  • Publication number: 20150145726
    Abstract: Apparatus for improving the performance and allowing increased directionality of reflecting-type antenna systems by varying the geometry of the reflecting surface. A reflecting surface is composed of an array of actuated pins which are capable of extending or retracting to alter the overall pattern. An actuator controlling unit has the address of each actuator and is able to extend or retract the pins to the desired degree. The specific pattern which the actuator control unit realizes is determined by the iterative position calculator which utilizes directional inputs from the user and/or inputs from a system which determines the effectiveness of previous pin movements. The apparatus attempts to maximize the received signal by assessing amplitude changes over time and utilizing that information to direct alteration in the reflecting surface for optimal performance.

  • Patent number: 9013362
    Abstract: The outdoor antenna includes multiple directors located respectively on a main rod and two assistant rods, and an inner-swing arm and an outer-swing arm fixed on the main rod and coupled with two ends of the assistant rods. When the inner-swing arm and the outer-swing arm are expanded, the assistant rods are fixed on two sides of the main rod; when the inner-swing arm and the outer-swing arm are folded, the assistant rods are positioned in parallel with the main rod. In use, the inner-swing arm and the outer-swing arm are expanded to allow the assistant rods to move toward the two sides of the main rod and maintain in a certain spatial distance to receive as many radio signals as possible. During transportation and storage, the assistant rods can lean against two sides of the main rod, so that occupied space is reduced to achieve usability.
