A method and apparatus for performing satellite signal acquisition are described. In one embodiment, a method for using a satellite antenna comprises estimating antenna orientation when the antenna is in motion, including estimating yaw using one or more sensors; and performing signal acquisition to search for a satellite signal with the satellite antenna by interleaving a plurality of signal searches performed by the satellite antenna, the plurality of signal searches being based on an estimated yaw.

Satellite signal acquisition

A system that improves wireless communication between a wireless base station and a plurality of remote wireless computing user devices (UEs) based on aiming downlink wireless signals from a base station in a beam shaped waveform in a determined direction for each remote UE that is identified as allocated a time period for communication with the base station according to a schedule. The system includes different types of components may be employed to implement various functions, including an angle of arrival (AoA) detector component, a downlink protocol decoder component, and an antenna controller component. The AoA detector component may be employed to monitor one or more radio frequency (RF) wireless signals radiated by UEs that are communicating with the base station in accordance with an allocation schedule.

Aimable beam antenna system

Filtering for sampled data representing uplink wireless RF signals monitored by a pair of antennas is provided to improve accuracy in determining an angular location of an identified UE. An extracted portion of the filtered sampled data is used to improve accuracy in determining an angular location of the identified UE. The extracted portion represents direct path uplink wireless RF signals that have traveled by a line of sight between the pair of antennas and the identified UE. Another portion of the filtered sampled data is cancelled, which represents multiple path (multipath) uplink wireless RF signals that have traveled a longer distance than the direct path signals due to reflection from one or more surfaces on multiple paths between the identified UE and the pair of antennas.

Multipath filtering for wireless RF signals

A method and apparatus is disclosed herein for acquiring and tracking a satellite signal with an antenna. In one embodiment, the method comprises a) perturbing one or more of roll, pitch and yaw angles of an antenna orientation to create variant orientations associated with a first search pattern; b) computing new scan and polarization angles, in response to perturbed roll, pitch and yaw angles, for each of the variant orientations; c) receiving a radio-frequency (RF) signal from a satellite for each of the variant orientations; d) generating one or more receiver metrics representing a received RF signal associated with each of the variant orientations; e) selecting, as a new orientation, one of the variant orientations based on the one or more receiver metrics; and f) repeating a)-e) with the new orientation with a second search pattern narrower than the first search pattern.

An antenna having radio-frequency (RF) resonators and methods for fabricating the same are described. In one embodiment, the antenna comprises a physical antenna aperture having an array of antenna elements, where the array of antenna elements includes a plurality of radio-frequency (RF) resonators, with each RF resonator of the plurality of RF resonators having an RF radiating element with a microelectromchanical systems (MEMS) device.
