  • Publication number: 20240313397
    Abstract: Examples disclosed herein relate to an antenna calibration method for a beam steering radar. A first set of input voltages is determined for a plurality of phase shifters coupled to a plurality of antenna elements in an antenna array in the beam steering radar, the voltages to control phases of signals for transmission by the antenna array. 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.

  • Patent number: 11128051
    Abstract: Examples disclosed herein relate to a multi-frequency electromagnetic feed line. The multi-frequency electromagnetic feed line includes a waveguide that has a plurality of slots arranged laterally along a length of the waveguide that corresponds to a first axis, in which the plurality of slots are configured to radiate electromagnetic signaling from an input end of the waveguide to a terminal end of the waveguide. The waveguide also has a plurality of vias arranged proximate to the terminal end of the waveguide in a predetermined angle relative to a second axis orthogonal to the first axis, in which the plurality of vias are configured to terminate the plurality of slots for different frequencies of an operating frequency band. A first slot of the plurality of slots that is arranged closest to the terminal end has varying distances to different vias. Other examples disclosed herein relate a method of fabricating a waveguide.

  • Publication number: 20200241122
    Abstract: Examples disclosed herein relate to a radar system for three-dimensional beam scanning that includes an antenna module that radiates radio frequency (RF) beams with an analog beamforming antenna in a plurality of directions using phase control elements and generates radar data capturing a surrounding environment from received RF return signals. The antenna module includes a first transceiver operational at a first frequency and configured to scan a field of view with first RF beams along a first axis, and a second transceiver operational at a second frequency and configured to scan the field of view with second RF beams along a second axis. The radar system also includes a perception module that detects and identifies a target in the surrounding environment from the radar data.
