  • Publication number: 20220399653
    Abstract: The present invention discloses a millimeter-wave dual circularly polarized lens antenna and electronic equipment. The antenna includes a broadband circularly polarized planar feed source array and a dual circularly polarized planar lens. In the planar feed source array, a double-layer stacked patch is used at the same time to achieve broadband circular polarization, and a sequentially rotating feed structure is used to further expand the bandwidth. In the planar lens, a miniaturized stacked patch and a microstrip true-time-delayed phase-shifting structure are used to obtain the independent regulation and control of the left-handed and right-handed circularly polarized wave transmissive phases in a relatively wide frequency band.

  • Patent number: 10969456
    Abstract: The disclosure describes embodiments for modifying an operation of a vehicle component based on a Vehicle-to-Everything (V2X) communication. In some embodiments, a method includes receiving, by a V2X receiver, a V2X message including context data that describes a context of a V2X transmitter in an environment, wherein the V2X receiver is not sufficiently able to identify the V2X transmitter as an originator of the V2X message within the environment. The method includes determining, by the V2X receiver, digital data describing an identity of the V2X transmitter as the originator of the V2X message within the environment based on the context data. The method includes modifying the operation of the vehicle component of the V2X receiver based on the digital data describing the identity of the V2X transmitter.

  • Patent number: 10181647
    Abstract: An antenna apparatus can include a transmission medium that is positioned within layers of an antenna apparatus that are positioned adjacent to a first upper layer that is configured to include a signal receiving and transmission element (e.g. an antenna, patch antenna, etc.). The transmission medium can include or otherwise be connected to one or more resonators so that only a signal within a pre-selected band is passable through the transmission band. Any signal in a band outside of the pre-selected band may not be passable through the transmission medium due at least in part to the resonators. In some embodiments, the transmission medium may be part of a stripline or a microstrip. Embodiments of the apparatus may also be configured to block backward radiation emittable from the antenna to help prevent a body of a person near that device from absorbing such radiation.
