Examples disclosed herein relate to a node in a fixed wireless network. A controller determines optimal paths between nodes through relational calculations. Phase shifts are made to signals generated from one node to another according to the optimal path direction.

Fixed wireless systems and methods incorporating a beam steering antenna

Examples disclosed herein relate to a meta-structure based reflectarray for beamforming wireless applications and a method of operation of passive reflectarrays in an indoor environment. The method includes receiving, by a plurality of passive reflectarrays, a Radio Frequency (RF) signal from a source. The method also includes reflecting, by the plurality of passive reflectarrays, the RF signal to generate a plurality of RF beams to a respective target coverage area, in which each of the plurality of RF beams increases a multipath gain along a signal path between a corresponding passive reflectarray to the respective target coverage area.

Meta-structure wireless infrastructure for beamforming systems

A radar system for interacting with navigation targets is provided. The radar system is configured to interact with navigation targets (target devices) that shift the phase of a received radar transmission to generate a phase shifted response signal. Phase shifters (e.g., silicon germanium phase shifters) are designed to assign specific frequency responses from one or more navigation modules to identify target locations. The radar module transmits at a modulated signal at first frequency, each navigation target receives the radar transmission, phase shifts the signal and returns the phase shifted signal. Where two or more navigation targets are used, each will apply a different phase shift to the received radar transmission, wherein the frequency identifies the navigation target devices. In a radar system, the modulated transmission signal is compared to the returned phase shifted signal to determine a frequency difference between the two signals.

Examples disclosed herein relate to methods and apparatuses for an antenna structure having reactance control of an array of radiating elements to achieve radiation beam tilting.

Meta-structure antenna array

Examples disclosed herein relate to an antenna system. The antenna system has a transceiver unit adapted to receive a composite communication signal, wherein the composite communication signal is a mix of multiple individual communication signals transmitted at different frequencies, a radiating structure comprising multiple subarrays of radiating elements, each subarray responsive to a different frequency, and an antenna controller adapted to map each communication signal to a user equipment.

Method and apparatus for a frequency-selective antenna

Examples disclosed herein relate to an antenna system in a radar system for object detection with a sounding signal.

The antenna is configured to determine a location of the object and a mobility status from the set of reflections. The antenna controller is also configured to generate signaling indicating the location and mobility status of the object as output to identify a target object different from the object. Other examples disclosed herein relate to a radar system and a method of object detection with the radar system.

A first set of input voltages is applied to the antenna array. Radiating signals resulting from the first set of input voltages are measured. Voltage and phase values for the plurality of phase shifters are iteratively optimized to determine voltage and phase value pairs that result in a desired gain for the antenna array. The voltage and phase value pairs are stored in a look-up-table in the beam steering radar.
