  • Patent number: 11025377
    Abstract: A fixed wireless access system is implemented using orthogonal time frequency space multiplexing (OTFS). Data transmissions to/from different devices share transmission resources using—delay Doppler multiplexing, time-frequency multiplexing, multiplexing at stream and/or layer level, and angular multiplexing. Time-frequency multiplexing is achieved by dividing the time-frequency plan into subgrids, with the subsampled time frequency grid being used to carry the OTFS data. Antenna implementations include a hemispherical antenna with multiple antenna elements arranged in an array to achieve multiplexing.

  • Patent number: 10320092
    Abstract: A unit cell for an antenna comprises a conductive ground plane, a low-band radiator, a pair of high-band radiators, and a conductive partition disposed along an edge intersecting a pitch axis of the conductive ground plane. The low-band radiator comprises a pair of orthogonally coupled dipoles each having a vertical stem portion and an arm portion. Each arm disposed in a plane orthogonal to the conductive ground plane. The arm portions, collectively and on-edge, produce an L-shaped radiator parallel to the conductive ground plane. Each of the high band radiators comprises a pair of cruciform radiators, each cruciform electrically connected to, spaced-apart from, and parallel to the conductive ground plane. The conductive partition isolates at least a portion of the RF energy transmitted by the low and high-band radiators.

  • Patent number: 10224646
    Abstract: The present invention discloses an antenna radiating element and an antenna, where the antenna radiating element includes a pair of crosswise disposed dipoles and parasitic element assemblies; the parasitic element assembly is disposed in an included angle formed by two neighboring dipole arms of the crosswise disposed dipoles; the parasitic element assembly is fastened to the dipole; and a radiation signal transmitted by the dipole is reflected and converged by using the parasitic element assembly. In embodiments of the present invention, the antenna radiating element has a very simple structure, may be directly formed by sheet metal parts, and is convenient to process and manufacture. Also, the parasitic element assembly achieves an effect of reducing a volume of the entire antenna, and therefore both production costs and maintenance costs are reduced.

  • Patent number: 10170833
    Abstract: A transmitter or receiver can include a phased array antenna system in which multiple characteristics of a transmitted or received beam can be controlled electronically. For example, in embodiments that include a transmitter, dual outputs of N signal modifiers can be connected to orthogonal inputs of N dual-orthogonally polarized antenna elements. Each signal modifier can modify the amplitude and phase of a communications signal in two parallel signal paths to produce two signal components each of which is an amplitude-modified/phase-shifted version of the communication signal. Multiple characteristics of the combined beam can be simultaneously controlled by setting the amplitude and/or phase-shift parameter values in the dual signal paths in the signal modifiers to combined values that individually affect each of the multiple characteristics of the combined beam.
