  • Patent number: 10389032
    Abstract: Embodiments of a wide band multi-polarization antenna system are described, which can be attached to the back or front of a soldier's vest or backpack. The antenna system can allow for release of pre-shaped integral radiating elements that spring into a geometric configuration suitable for circular polarization radiation or linear polarization over a desired band of frequencies. The antenna system can provide, when collapsed, linear polarized line-of sight capability over a wide band of frequencies. In a collapsed low-profile state, the antenna system can remain on the soldier, but out of the way for maneuvering.

  • Patent number: 10367254
    Abstract: A space-based phased antenna array provides one- or two-dimensional beam steering, yet is compact upon launch and does not require gravity to maintain its shape or orientation. An exemplary antenna array includes a central satellite and at least three peripheral satellites. Each peripheral satellite is mechanically connected to the central satellite by an extendible tether. At launch, the tethers are retracted, so the peripheral satellites are close to, or within, the central satellite. Once in position, the central satellite rotates and extends the tethers, thereby deploying the peripheral satellites in a planar radial pattern. Multiple antenna elements, some disposed on each tether, collectively form a planar phased array that can be electronically beam steered in two dimensions. The antenna array may relay signals, such as between local companion satellites or planet-based stations, and earth. Linear versions, with as few as two tethered satellites, are beam steerable in one dimension.

  • Patent number: 10348372
    Abstract: A technique for improving wireless communication characteristics involving matching transmitter antenna patterns to receiver antenna patterns. In a specific implementation, the transmitter antenna pattern adapts to changing parameters, such as when a smartphone is initially held in a first orientation and is later held in a second orientation. Because the transmitter antenna patterns match the receiver antenna patterns, signal quality between stations improves. In some implementations, antennas are organized and mounted to maximize spatial diversity to cause peak gains in different directions.

  • Patent number: 10333198
    Abstract: An antenna apparatus includes a conductive radiating element, a conductive member, and a first impedance circuit. The first impedance circuit includes a first parallel resonant circuit (an LC parallel resonant circuit) and is directly connected between the radiating element and the conductive member (the conductor plate). Since the first parallel resonant circuit has high impedance in its resonant frequency band and is equivalently in an open state, one end of the radiating element is opened in the resonant frequency band. Accordingly, the radiating element defines and functions as a standing-wave antenna that contributes to electric-field radiation and a loop portion including the radiating element, the conductive member, and the first impedance circuit defines and functions as a magnetic-field radiation antenna that contributes to magnetic-field radiation.
