    摘要: Systems relating to antennas. Antenna elements are coupled to adjacent other antenna elements by way of a coupler. The coupled antenna elements may be part of the same antenna array. The coupler may take the form of a substrate with conductive traces and the antenna elements may be dipoles or crossed dipole antennas. The coupled antenna elements may have similar polarizations. The capacitive coupling allows for physically smaller reflectors for antenna arrays.

    摘要: Systems and methods relating to multi-beam forming networks using an antenna array. A matrix circuit for feeding elements of an antenna array to produce multiple beams is provided. To address beam squint issues, beam squint is mitigated by using a series of phase shifters with specific phase-delay performances between the matrix circuit and the antenna array elements. A linearly increasing or decreasing phase difference in the signals fed into adjacent antenna array elements across the array mitigates or eliminates beam squint in the resulting multiple beams. The phase shifters are programmed to provide this increasing or decreasing phase differences.

    摘要: An antenna comprising a plurality of spatial bandpass structures, wherein each spatial bandpass structures comprises an LC resonator having at least one parasitic patch disposed within a loop of the resonator. The plurality of spatial bandpass structures is positioned around a central section of the antenna. In some embodiments, each spatial bandpass structure is embedded in a radiating arm of an antenna. In some embodiments, the central section comprises at least one radiator. In some embodiments, the antenna further comprises at least one parasitic radiator disposed between two spatial bandpass structures. In other embodiments, the antenna has only one spatial bandpass structure, and/or is configured unevenly (i.e., such that different sides of the antenna are configured differently).
