    摘要： A beam forming network system includes a first beam forming network having first and second ports, in which each of the first ports is operatively coupled to an antenna element; and a second beam forming network including third and fourth ports, in which each of the third ports is operatively coupled to one of the second ports using at least one of a phase shifter, attenuator, power divider, and/or hybrid coupler. A method of beam forming includes coupling each of the first ports associated with a first beam forming network operatively to one antenna element, and coupling each of the third ports associated with a second beam forming network operatively to one of the second ports associated with the first beam forming network using at least one of a phase shifter, attenuator, power divider, and/or hybrid coupler.

    摘要： An antenna array system provides simultaneous 360° coverage and includes Butler matrix beam forming networks connected to an antenna array, which includes narrow and/or broadband elements, and multiple transmitters, receivers, or transceivers to allow for 360° transmission and/or reception. The antenna array system can provide multiple beams, such as without limitation 8 or 16 beams, which can vary in beam crossing and/or overlap to provide simultaneous 360° coverage. An antenna array system includes a plurality of antenna elements configured in an array, a first Butler matrix operatively coupled to the plurality of antenna elements, and a second Butler matrix operatively coupled to the first Butler matrix. A method of providing simultaneous 360° coverage includes configuring a plurality of antenna elements in an array, coupling a first Butler matrix operatively to the plurality of antenna elements, and coupling a second Butler matrix operatively to the first Butler matrix.
