摘要： A vertically polarized traveling wave antenna forms peanut-type directional lobes without significant nulls between the lobes. A self-supporting coaxial line feeds quad-dipole bays coupled around the coaxial line, with opposed dipole pairs spaced along the coaxial line. Matched-layer spacing provides substantial cancellation of the reactive components of the loads. Dipoles are oriented parallel to the coaxial line axis, with opposite “hot” (center coupled) elements oppositely oriented. Radiated signals have rotating phase. Changing the spacing within quads from a quarter wavelength or rotating the second dipole pair of each quad away from a right angle causes the antenna to radiate strongly on one axis and weakly at right angles thereto, without the nulls of back-to-back panel antennas.

摘要： A structural printed wiring board panel includes a multilayer printed wiring board having opposing, outer faces and interlayer interconnects that route RF, power and control signals. Connection areas are formed in or on at least on one face for connecting the interlayer interconnects and any electrical components. A metallic face sheet is secured onto at least one outer face, adding structural rigidity to the multilayer printed wiring board. A metallic face sheet can have apertures positioned to allow access to connection areas. RF components can be carried by a face sheet and operatively connected to connection areas. Antenna elements can be positioned on the same or an opposing face sheet and operatively connected to RF components to form a phased array printed wiring board (PWB) panel,

摘要： Improved phased array techniques and architectures are provided. For example, a linear phased array includes N discrete phase shifters and N−1 variable phase shifters, wherein the N−1 variable phase shifters are respectively coupled between adjacent output nodes of the N discrete phase shifters such that the N discrete phase shifters reduce an amount of continuous phase shift provided by the N−1 variable phase shifters. Each of the N discrete phase shifters may select between two or more discrete phase shifts. The N discrete phase shifters also preferably eliminate a need for a variable termination impedance in the linear phased array.

摘要： An antenna array may be constructed using a plurality of tubes of electrically conducted material in conjunction with an additionally electrically conductive component which covers the front faces of tubes and at least part of the sides. Between the structures, a further electrically conductive material may be placed separated by dielectric material, and may be used to provide radiating elements and a feed structure by producing stripline structures. This structure is thereby able to reduce cavity back slots fed with triplate stripline along the sides of the tubes. This structure, particularly when made from plastics material, is low in complexity and cost and lightweight. These features overcome many of the disadvantages of the existing designs.

摘要： An antenna concept for radiating intense, high power electromagnetic fields in the RF regime without electrical breakdown. The invention accomplishes this with high aperture and power efficiency, high gain, and in a geometry that is compact and conformal to a planar or curved surface. The antenna concept is compatible with standard rectangular waveguide feeds, or other hybrid transmission line geometries.

摘要： A traveling-wave combining array antenna apparatus includes first and second traveling-wave array antennas. The first traveling-wave array antenna has a plurality of antenna elements provided at intervals along a first feeder line, and has a radiating directivity characteristic. The second traveling-wave array antenna has a plurality of antenna elements provided at intervals along a second feeder line, and has a main beam of a half-value width and a radiating directivity characteristic of a side lobe level lower than that of the first traveling-wave array antenna. A transmitting signal is split into two signals, feeding the signals to the first and second traveling-wave array antennas, which are provided so that a variation of main-beam radiating angle of electromagnetic wave of transmitting signal radiated from the first traveling-wave array antenna corresponding to a frequency change, and that of the second traveling-wave array antenna are substantially canceled by each other.

摘要： A microelectromechanical system (MEMS) steerable electronically scanned lens array (ESA) antenna and method of frequency scanning are disclosed. The MEMS ESA antenna includes a wide band feedthrough lens and a continuous transverse stub (CTS) feed array. The wide band feedthrough lens includes first and second arrays of wide band radiating elements and an array of MEMS phase shifter modules disposed between the first and second arrays of radiating elements. The continuous transverse stub (CTS) feed array is disposed adjacent the first array of radiating elements for providing a planar wave front in the near field. The MEMS phase shifter modules steer a beam radiated from the CTS feed array in two dimensions.
