摘要： [Problems to be Solved]
To provide a flight vehicle and a communication system which can relay communications between transmission and reception antennae that are located farther from each other by using antennae capable of receiving information transmitted from a transmission antenna located in a wider range than a range of a linear directed antenna can receive.
[Solution]
A flight vehicle 1 according to the present invention comprises one or more linear array antennae (antennae 4); and a controller 2 configured to be capable to execute: a process of receiving information by one or more of the antennae 4, a process of outwardly transmitting said information by one or more of the antennae 4. In the communication system C of the present invention, which includes said flight vehicle 1, the transmission antenna T1 and the reception antenna R1 differ from each other. In the flight vehicle 1 of the present invention, it is preferable that the antennae 4 that receives the information and the antennae 4 that transmits the information differ from each other.

摘要： Embodiments provide in-flight configuration of satellite pathways to flexibly service terra-link and cross-link traffic in a constellation of non-processed satellites, for example, to facilitate flexible forward-channel and return-channel capacity in a satellite communications system. For example, each satellite in the constellation can include one or more dynamically configurable pathway and switching and/or beamforming can be used to configure each pathway to be a forward-channel pathway or a return-channel pathway in each of a number of timeslots according to a pathway configuration schedule. At least some of the pathways can be further selectively configured, in each timeslot, to carry “terra-link” traffic to and/or from terrestrial terminals and “cross-link” traffic to and/or from one or more other satellites of the constellation.

摘要： A radome structure for a multilayered broadband radome structure is described. The radome structure may include a central core layer comprising a first dielectric constant, an interior intermediate core layer adjacent to an interior side of the central core layer, comprising a second dielectric constant less than the first dielectric constant, an exterior intermediate core layer adjacent to an exterior side of the central core layer, comprising a third dielectric constant less than the first dielectric constant, and an interior outside core layer adjacent to an interior side of the interior intermediate core layer, comprising a fourth dielectric constant less than the second dielectric constant. In some examples of the radome structure described above may further include an exterior outside core layer adjacent to an exterior side of the exterior intermediate core layer, comprising a low dielectric constant.

摘要： An antenna structure of reduced size but able to operate at multiple frequencies, and applied to an electronic device, includes a housing, a first feed point, a first radiation portion, a first ground point, a second radiation portion, and a second feed point. The housing has at least one portion made of metal material with first and second gaps therein. The housing between first and second gaps forms the first radiation portion. The first feed point feeds current and signal to the first radiation portion. The first ground point is spaced from the first feed point and is grounded through a first inductive element. The second radiation portion is adjacent to the first radiation portion. The second feed point is electrically connected to a second signal point and feeds current and signal to the second radiation portion.

摘要： An antenna system for an unmanned aerial vehicle (UAV) includes one or more antennas, a reflector, and a control system. The control system is configured to determine a density of antenna towers near the UAV, determine a position for an active antenna of the one or more antennas based on the density, and adjust the active antenna to the determined position. In some embodiments, the antenna system further includes one or more switches, each of the one or more antennas is a different distance from the reflector, and the switches are used to adjust the active antenna to the determined position by selecting a one of the one or more antennas closest to the determined position as the active antenna. In some embodiments, the antenna system further includes an actuator and the active antenna is moved to the determined position using the actuator.

摘要： An aviation antenna assembly may include a plurality of antenna elements, a directional control switch associated with each of the antenna elements to enable each of the antenna elements to transition between transmitting via a transmission via a transmit chain or receive via a receive chain, beam forming network elements disposed in the transmit chain and the receive chain, and an electronically controlled phased array stirring assembly operably coupled to the directional control switch of each of the antenna elements and to the beam forming network elements to perform electrical stirring with respect to signals in the transmit chain and the receive chain. The antenna elements, the directional control switch, the beam forming network elements, and the electronically controlled phased array stirring assembly of the antenna assembly are all disposed within a single radome attachable to an aircraft body.

摘要： An antenna system for space applications provides a membrane antenna with one or more flexible membranes. An antenna enclosure stores the membrane antenna during stowage. One or more first deployable support structures extend along a first axis from the antenna enclosure during deployment, at least a first point of the membrane antenna being operably anchored to a point on the first deployable support structures. Deployment mechanisms are operably anchored at a junction with the first deployable support structures. The deployment mechanisms extend one or more second deployable support structures along a second axis from the first deployable support structures during deployment. At least a second point of the membrane antenna is operably anchored to a point on the second deployable support structures. Extension of the first deployable support structures and second deployable support structures unfurls the membrane antenna along both axes to overlap the junction.

摘要： A vehicle, vessel or airplane having an antenna and a motor rotating the antenna, a rotation encoder outputting information relating to the rotation and outputting the information to two controllers of which one controls the motor. The other controller receives the rotation information and information relating to a position/direction/axis in relation to the vehicle/vessel/airplane and outputting a second signal based thereon. The output of the second controller may be used for controlling the motor to have the antenna directed toward e.g. a satellite irrespective of the motion of the vehicle/airplane/vessel.
