  • Patent number: 10381704
    Abstract: An electromagnetic coupler that couples antenna signals for a wideband antenna positioned between glass layers of an automotive windshield. The coupler includes a first co-planar waveguide (CPW) formed on one side of a glass layer and a second CPW formed on the other side of the glass layer, where the first and second CPWs are a mirror, or near-mirror, and 180° rotated images of each other. Both the first and second CPWs include a conductive plane where removed portions of the plane define a wide CPW section and a narrow CPW section that are electrically coupled to each other, and where the remaining portions of the conductive plane are ground planes, and where the electromagnetic signals are coupled through the glass layer between the wide CPW sections.

  • Publication number: 20190018121
    Abstract: A lidar system includes a light source to generate a frequency modulated continuous wave (FMCW) signal, and a waveguide splitter to split the FMCW signal into an output signal and a local oscillator (LO) signal. A transmit coupler provides the output signal for transmission. A receive lens obtains a received signal resulting from reflection of the output signal by a target. A waveguide coupler combines the received signal and the LO signal into a first combined signal and a second combined signal. A first phase modulator and second phase modulator respectively adjust a phase of the first combined signal and the second combined signal to provide a first phase modulated signal and a second phase modulated signal to a first photodetector and a second photodetector. A processor processes a first electrical signal and a second electrical signal from the first and second photodetectors to obtain information about the target.
