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.

摘要： An antenna array includes a plurality of antenna elements coupled in a common area and extending radially outward from the common area. At least one of the plurality of antenna elements includes a first antenna portion and a second antenna portion arranged in a configuration such that a gap is formed between the first antenna portion and the second antenna portion. The gap includes first spacing associated with a first operating frequency and a first operating wavelength, and a second spacing associated with a second operating frequency and a second operating wavelength. A proportion of the first spacing to the first wavelength is substantially equal to a proportion of the second spacing to the second wavelength, thereby providing a constant beamwidth over an operating frequency band. A method of arranging a plurality of antenna elements in an antenna array is also disclosed.

摘要： A frame assembly for a filter or the like which is adapted to be inserted in apertures of buildings such as windows or doors or the like. The frame assembly is telescopically adjustable in two different directions for being accommodated by different size and shape apertures, and is provided with an elongate clamp at each telescopically adjustable portion for holding the adjustment and for rigidity and strength. A filtering material is disposed within the frame assembly and is provided with a retaining screen at each of its major surfaces.

摘要翻译： 用于过滤器等的框架组件，其适于插入诸如窗户或门等的建筑物的孔中。 框架组件可以在两个不同的方向上可伸缩地调节，以便通过不同的尺寸和形状的孔容纳，并且在每个可伸缩调节部分处设置有用于保持调节和刚度和强度的细长夹具。 过滤材料设置在框架组件内并且在其主要表面的每一个处设置有挡板。
