摘要: Provided herein are various improvements to antenna stabilization systems, such as employed on confocal phased array reflector antenna arrangements. In one example, a system includes a feed structure for a main reflector, the feed structure comprising an electronically scanned array (ESA) feed and a sub-reflector. The sub-reflector is configured to propagate a signal between the ESA feed and the main reflector. The system also includes a star tracker element coupled to the feed structure and configured to determine orientation information relative to star alignment, and laser distancing elements coupled to the feed structure and configured to determine distance measurements relative to the main reflector. A control system is configured to determine pointing errors of the main reflector based at least on the orientation information and the distance measurements, and these pointing errors can be used by the ESA feed to adjust steering of a signal towards a target.

摘要: A base station antenna includes a radome and an antenna assembly that is mounted within the radome. The antenna assembly includes a backplane that includes a first reflector, a first array that includes a plurality of first radiating elements mounted to extend forwardly from the first reflector, a second reflector mounted to extend forwardly from the first reflector and a second array that includes a plurality of second radiating elements mounted to extend forwardly from the second reflector. The first radiating elements extend a first distance forwardly from the first reflector and the second radiating elements extend a second distance forwardly from the second reflector, where the first distance exceeds the second distance.

摘要: A base station antenna includes: a plurality of reflector panels; a plurality of printed circuit boards (PCBs), each of the circuit boards mounted on a respective one of the reflector panels; a plurality of radiating elements mounted on each of the PCBs, wherein the PCBs and the radiating elements are configured and arranged so that the base station antenna receives and transmits radio frequency signals in a first frequency band and a second frequency band; first and second wiper members pivotally mounted on each PCB at respective first and second pivots, the first and second wiper members being configured such that pivotal movement of the first and second wiper members induce downtilt angle adjustment in the radiating elements that transmit and receive signals in first frequency band; third and fourth wiper members pivotally mounted on each PCB at respective third and fourth pivots, the third and fourth wiper members being configured such that pivotal movement of the third and fourth wiper members induce downtilt angle adjustment in the radiating elements that transmit and receive signals in a second frequency band; and a phase shifter linkage comprising a first carrier member and a second carrier member fixed relative to the first carrier member, the first carrier member engaging the first and second wiper members and the second carrier member engaging the third and fourth wiper members. Actuation of the phase shifter linkage causes the first carrier member and the second carrier member to move in concert relative to the PCBs, so that downtilt angle adjustment of the first frequency band equals downtilt adjustment of the second frequency band.

摘要: Wireless communications systems and methods related to information associated with a reconfigurable intelligent surface (RIS) in a wireless communication network are provided. For example, a method of wireless communication performed by a wireless communications device may include transmitting, to a reconfigurable intelligent surface (RIS), a request for information associated with the RIS and receiving, from the RIS, the information. Other features are also claimed and described.

摘要: Disclosed embodiments relate to communicating with satellites at any elevation. In one example, an antenna system includes two or more user terminal panels (UTPs). Each of the UTPs include multiple user terminal modules (UTMs). The UTPs may be arranged in either a fixed, an adjustable geometry or a combination thereof. A UTM has multiple user terminal elements (UTEs) that include antennas and active circuits. An antenna may either generate an incoming signal in response to incident radio waves received from a satellite and/or may transmit an outgoing signal toward the satellite. Each active circuit is configured to process the incoming and outgoing signals. Also, the antenna system may include a control circuit configured to control signal processing performed by the active circuits. The UTPs may be operably connected to a single satellite, or different UTPs may be operably connected to different satellites.

摘要: An illustrative example detector for use on a vehicle includes a radiation emitter having a near field region that is defined at least in part by a wavelength of radiation emitted by the radiation emitter. A radiation steering device includes a plurality of reflectors, an actuator, and a controller. The reflectors are situated to reflect the radiation emitted by the radiation emitter. The reflectors are in the near field region and have at least one characteristic that limits any phase shift of the reflected radiation. The actuator is configured to adjust an orientation of the reflectors. The controller is configured to determine an orientation of the plurality of reflectors relative to the radiation emitter to steer the emitted radiation reflected from the reflectors in a determined direction. The controller is configured to control the actuator to achieve the determined orientation.

摘要: An antenna device includes an antenna unit and reflecting units. The antenna unit is arranged on a substrate. The reflecting units are arranged separately from each other on the substrate and surrounding the antenna unit. The reflecting units are configured to adjust a radiation pattern of the antenna unit, and each of the reflecting units includes a first portion and a second portion. The first portion has an upper side and a lower side, and the lower side of the first portion is coupled to the substrate. The second portion has a lower side connected to the upper side of the first portion. A width of the lower side of the first portion is smaller than a width of the lower side of the second portion.
