  • Patent number: 11381441
    Abstract: A millimeter-wave communication system includes a transmitter and a receiver. The transmitter is configured to be connected to a waveguide that is transmissive at millimeter-wave frequencies, the waveguide having a propagation parameter that varies with frequency at the millimeter-wave frequencies. The transmitter is configured to generate a millimeter-wave signal comprising multiple sub-carriers that are modulated with data, wherein each sub-carrier is modulated with a respective portion of the data and is subjected to only a respective fraction of a variation in the propagation parameter, and to transmit the millimeter-wave signal into a first end of the waveguide. The receiver is configured to receive the millimeter-wave signal from a second end of the waveguide, and to extract the data from the multiple sub-carriers.

  • Patent number: 11128375
    Abstract: A millimeter-wave communication device includes a coupler, Radio-Frequency (RF) circuitry and a composite right/left-handed metamaterial assembly. The coupler is configured to connect to a waveguide, the waveguide being transmissive at millimeter-wave frequencies and having a given dispersion characteristic over a predefined band of the millimeter-wave frequencies. The RF circuitry is configured to transmit a millimeter-wave signal into the waveguide via the coupler, or to receive a millimeter-wave signal from the waveguide via the coupler, and to process the millimeter-wave signal. The composite right/left-handed metamaterial assembly is formed to apply to the millimeter-wave signal, or to an Intermediate-Frequency (IF) signal corresponding to the millimeter-wave signal, a dispersion compensation that compensates for at least part of the dispersion characteristic of the waveguide over the predefined band.
