  • Method and apparatus for monitoring and compensating for environmental and other conditions affecting radio frequency liquid crystal
    Patent number: 10985457
    Abstract: Monitoring and compensating for environmental and other conditions affecting antenna elements of an antenna is described. The conditions may affect radio frequency (RF) liquid crystal of the antenna elements. In one embodiment, the antenna comprises a physical antenna aperture having an array of surface scattering antenna elements that are controlled and operable together to form a beam for the frequency band for use in holographic beam steering and a compensation controller to perform compensation on the antenna elements based on monitored antenna conditions.
    Type: Grant
    Filed: September 10, 2019
    Date of Patent: April 20, 2021
    Assignee: KYMETA CORPORATION

  • Beam shaping for reconfigurable holographic antennas
    Patent number: 10566697
    Abstract: A reconfigurable holographic antenna and a method of shaping an antenna beam pattern of a reconfigurable holographic antenna is disclosed. A baseline holographic pattern is driven onto a reconfigurable layer of the reconfigurable holographic antenna while a feed wave excites the reconfigurable layer. An antenna pattern metric representative of a baseline antenna pattern is received. The baseline antenna pattern is generated by the reconfigurable holographic antenna while the baseline holographic pattern is driven onto the reconfigurable layer. A modified holographic pattern is generated in response to the antenna pattern metric. The modified holographic pattern is driven onto the reconfigurable layer of the reconfigurable holographic antenna to generate an improved antenna pattern.
