  • Patent number: 11710905
    Abstract: The disclosed method may include (1) determining a current physical state regarding an antenna assembly that includes (a) a sub-reflector that receives a wireless signal and reflects the wireless signal to a feed structure for processing, (b) a continuous antenna reflector that receives the wireless signal at a reflecting surface that reflects the wireless signal to the sub-reflector, where the current physical state is indicative of a current surface error over the reflecting surface relative to the sub-reflector, and (c) a backing structure coupled to a back surface of the continuous antenna reflector opposite the reflecting surface and having a plurality of actuators distributed over, and coupled to, the back surface, (2) operating each of the plurality actuators in a manner that reduces the current surface error based on the current physical state. Various other methods and systems are also disclosed.

  • Publication number: 20190245265
    Abstract: The disclosed apparatus may include (1) an antenna assembly defining an upper cavity with an aperture, the antenna assembly further defining a lower cavity coupled to the upper cavity via a channel along a linear edge of the antenna assembly, where the antenna assembly may include a reflective element within the lower cavity having a concave parabolic contour, and (2) an array assembly positioned in the aperture and including an array of passive elements. The reflective element may transform a divergent radio frequency (RF) beam directed toward the concave parabolic contour within the lower cavity into a collimated RF beam propagating within the lower cavity and into the upper cavity via the channel, and the array of passive elements may radiate a transmitted RF beam from the aperture in response to the collimated RF beam in the upper cavity. Various other apparatuses, methods, and systems are also disclosed.

  • Patent number: 10355777
    Abstract: Systems and associated methods for adaptive beam aggregation in wireless communications between unmanned aerial vehicles (UAVs) and ground-based stations are disclosed herein. In some embodiments, a method for transmitting wireless data between an unmanned aerial vehicle (UAV) and a customer premise equipment (CPE) station includes transmitting a first wireless data between a first antenna array and a first CPE station and transmitting a second wireless data between a second antenna array and a second CPE station. The first and second antenna arrays can include one or more individual antennas of the UAV.
