  • Publication number: 20200088884
    Abstract: A vehicle, Lidar system and method of detecting an object is disclosed. The Lidar system includes a photonic chip, and a laser integrated into the photonic chip. The laser has a front facet located at a first aperture of the photonic chip to direct a transmitted light beam into free space. A reflected light beam that is a reflection of the transmitted light beam is received at the photonic chip and a parameter of the object is determined from a comparison of the transmitted light beam and the reflected light beam. A navigation system operates the vehicle with respect to the object based on a parameter of the object.

  • Publication number: 20200088845
    Abstract: A Lidar system, photonic chip and method of detecting an object is disclosed. The Lidar system includes the photonic chip. The photonic chip includes a laser and a local oscillator waveguide. The laser is integrated into the photonic chip and generates a leakage energy at a back facet of the laser for use as a local oscillator beam for the photonic chip. The local oscillator waveguide receives the leakage energy as the local oscillator beam. The laser further generates a transmitted light beam through a front facet of the photonic chip, combining the leakage energy with a reflection of the transmitted light beam form an object, and detects a combination of the reflected light beam and the leakage energy to determine a parameter of the object.

  • Patent number: 10490877
    Abstract: A thin film, flexible antenna that has particular application to be adhered to vehicle glass, where the antenna is operable to receive right-hand or left-hand circularly polarized signals from, for example, GPS and SDARS satellites. The antenna is a printed planar antenna formed to the substrate and includes a ground plane having an outer perimeter portion defining a slot therein and having a plurality of sides. A T-line tuning stub extends from one of the sides into the slot, a curved spur-line tuning stub extends from a corner where two sides of the perimeter portion meet and extends into the slot, and a radiating element electrically isolated from the perimeter portion extends into the slot. The perimeter portion is operable to generate circularly polarized signals to be received by the radiating element where the tuning stubs provide phase tuning of the circularly polarized signals.

  • Patent number: 10446907
    Abstract: An antenna assembly including a planar antenna formed on a dielectric substrate and a frequency selective impedance surface formed on the substrate and at least partially surrounding the antenna. The frequency selective impedance surface receives surface waves propagating along the dielectric substrate generated by the antenna, where the impedance surface mitigates negative effects of the surface waves by converting the surface wave energy into leaky-wave radiation, and also possibly providing some control of the radiation gain pattern of the antenna. In one embodiment, the dielectric substrate is vehicle glass, such as a vehicle windshield.
