  • Patent number: 11121465
    Abstract: A steerable beam antenna includes a feed line and first and second arrays of switchable scatterers along opposite sides of the feed line. The first array scatters an electromagnetic wave propagating through the feed line to form a first beam portion with a first polarization, and the second array scatters the propagating wave to form a second beam portion with a second polarization orthogonal to the first polarization. Each scatterer in the first and second arrays is switchable between a high state and a low state, the high state scatterers and the low-state scatterers in each of the first and second arrays defining a periodic pattern. The scatterers in the first and second arrays are switchable to shift the pattern of scatterers in one of the arrays relative to the pattern in the other array by a selectable period shift that yields a desired polarization for the beam.

  • Patent number: 10921442
    Abstract: A sensor has an antenna. The antenna includes a radiation source and a wave guide. The radiation source is formed on a substrate. The wave guide internally propagates electromagnetic waves radiated from the radiation source and radiates the electromagnetic waves as a beam. The wave guide has a radiation-side opening in which a first direction and a second direction are orthogonal to each other, and the second direction is longer than the first direction. In a cross-sectional shape of the beam, perpendicular to a radiation direction of the beam radiated from the wave guide, a first direction and a second direction are orthogonal to each other, and the second direction is narrower than the first direction.

  • Patent number: 10923804
    Abstract: An exemplary antenna system has first and second antenna elements, where a diplexer is connected to each second element. First phase shifters are connected to the first elements and to the diplexers, and second phase shifters are connected to the diplexers, but not to the first elements. Either a different bandpass filter is connected to the first and second phase shifters or a single multiplexer is connected to all phase shifters. The antenna system can be used to support communications over first and second sub-bands with independent beam tilts and equivalent beamwidths, where all of the elements are used for the first sub-band, and the second elements, but not the first elements, are used for the second sub-band. Each first element is separated from an adjacent element by a first distance, and each second element is separated from an adjacent element by a second distance different from the first distance.

  • Patent number: 10877124
    Abstract: Methods and systems for spatial filtering transmitters and receivers capable of simultaneous communication with one or more receivers and transmitters, respectively, the receivers capable of outputting source directions to humans or devices. The methods and systems use spherical wave field partial wave expansion (PWE) models for transmitted and received fields at antennas and for waves generated by contributing sources. The source PWE models have expansion coefficients expressed as functions of directional coordinates of the sources. For spatial filtering receivers a processor uses the output signals from at least one sensor outputting signals consistent with Nyquist criteria representative of the wave field and the source PWE model to determines directional coordinates of sources (wherein the number of floating point operations are reduced) and outputs the directional coordinates and communications to a reporter configured for reporting information to humans.

  • Patent number: 10859664
    Abstract: A direction finding (DF) system and technique using a switched network architecture to couple a first plurality of antenna elements to a second, fewer, plurality of channels of an RF receiver. The RF receiver provides signals to a DF processor which combines data sampled at phase centers of the plurality of array elements. Such combined data samples may be used to estimate a direction of a received signal. The antenna elements may be configured into subarrays and a switch network couples different groups of subarrays to the RF receiver channels during different dwell times. Data collected during each dwell may be used to generate a spatial sample covariance matrix (SCM) and multiple spatial SCMs may be combined to provide aggregate covariance matrix values. A DF processor uses values from the aggregate covariance matrix to provide an output signal indicative of the direction of a received signal.
