Latest Patents

One of his latest patents is for a wireless device with a 3-D antenna system. This invention discloses techniques for improving coverage of an antenna system. The wireless device includes a 3-D antenna system designed to enhance performance and coverage. The 3-D antenna system features antenna elements formed on multiple planes, each pointing in different spatial directions. These elements are associated with different antenna beams, providing a larger line-of-sight (LOS) coverage for the device. Additionally, beamforming can be performed for antennas on a given plane to further improve LOS coverage. The invention also addresses non-LOS (NLOS) coverage, as antenna beams pointing in various directions can result in reflected signals of higher power levels.

Another significant patent involves an integrated circuit for mixing millimeter-wavelength signals. This integrated circuit includes millimeter-wavelength transceiver circuitry, which features a local oscillator generating a millimeter-wavelength oscillator signal. The circuitry also includes mixers that convert signals based on this oscillator signal, all while being situated in an area without millimeter-wavelength structures.
