摘要： A non-dispersive antenna feed in which a length of strip transmission line (stripline) has two spaced center conductors supported on a dielectric sheet between two ground planes. These center conductors or conductive strips produce an even-mode electric field between the two ground planes when excited in-phase and an odd-mode electric field when the center conductors are excited in anti-phase relationship. A plurality of close-coupled quarter wave conductors parallel one of the center conductors, a feed strip extends substantially orthogonally from each such coupling strip to provide an antenna element feed externally. A four poor hybrid has two external ports and two additional ports for discretely feeding the stripline center conductors in-phase corresponding to excitation of one hybrid external port an in anti-phase corresponding to excitation of the other hybrid port. Each external hybrid port thereby corresponds to a different angle of antenna beam generation.

摘要： An integrated planar antenna array comprising at least two separate interleaved arrays separately controllable and responding to separate frequency bands. Both arrays operate with substantially the same phase center and substantially within the same effective aperture. The first array or subarray comprises spaced linear, slotted-waveguide arrays and the second subarray includes a meander line occupying the space between each of the waveguides of the first array. Scan systems are shown for independent operation of the two arrays. An alternative for the second subarray is shown in the form of slotted, square-coaxial, linear arrays in the spaces between the waveguides of the first subarray.

摘要： A space-fed phased-array arrangement in which the plural antenna elements each include first and second (front and rear) individual radiators. Between these input and output radiators, there is a combined controllable phase shifter and controllable electronic switching arrangement. In accordance with external control signals, the amount of phase shift (phase delay) introduced by each element may be controlled, and by appropriate programming of these phase shifts, beam formation and pointing angle may be determined. The electronic switch devices are programmable to convert any or all of the antenna elements to reflector or retro-directing elements whereby a rear-pointing beam may be generated and scanned in substantially the same way as the forward beam is generated and scanned. In the retro-directive (reflective) mode, energy from the primary feed passes bi-directionally through the reciprocal controllable phase shifter sections.

摘要： Methods of fabricating air-dielectric true-time-delay, continuous transverse stub array antenna. The first method uses conventional machining or molding techniques to fabricate layers of plastic with desired microwave circuit features. The plastic layers are then metalized, assembled (aligned) and joined together, such as by using ultrasonic welding techniques. Readily available metalization and ultrasonic welding techniques exist that may be used. The second method uses sheets of metal, into which microwave circuit features are fabricated, such as by machining. The layers are then assembled (aligned) and joined together, using one of several available processes, such as an inert gas, furnace brazing technique, for example.

摘要： Spatial thinning in no more than two dimensions is used in order to lower both the effective dielectric constant and the dielectric loss tangent of ferroelectric ceramics, while retaining a substantial fraction of their tunability. By not thinning in the third direction, along which the dc bias field is applied, the ferroelectric material maintains the connectivity between elements of the ferroelectric structure that is essential to retaining the tunability. Examples of one-dimensional structures (30) include small diameter columns (28, 32) of dielectric material embedded in a dielectric matrix (26, 34). Examples of two-dimensional structures (21) include square (22) and hexagonal (24) cells comprised of ferroelectric material filled with inert dielectric material or vice versa.

摘要： A broadband antenna system utilizes multiple photonic bandgap crystals to achieve nearly 100 percent power efficiency over a larger range of frequencies than prior antenna systems. Multiple custom tailored photonic bandgap crystals form a substrate for the antenna system. Each of the crystals is designed to cover a specific range of frequencies. The multiple crystals are attached together to form a photonic bandgap substrate whose bandwidth varies as a function of location on the substrate. A broadband antenna that can cover a wide frequency range, and whose active region shifts to different portions of the antenna as a function of frequency, is formed on the substrate such that the active region of the antenna is always on a crystal that has a corresponding operating bandwidth. The photonic bandgap crystals provide a nearly 100 percent efficient reflector for radiation emitted into the substrate that would otherwise be trapped or dissipated therein.

摘要： An annular rotary RF coupler for installation about a vertical support structure, particularly the mast of a ship. Two annular troughs are regularly divided in circumferential increments providing a cellular structure of individual waveguide cross-sections. A lower annulus remains fixed, the individual waveguide sections therein being fed from a power-divided, equal-phase, feed configuration. The oppositely facing upper annulus rotates with respect to the lower one about a common mechanical center of rotation of a mechanically rotating antenna system. Connection to the rotating waveguide sections may be through power combiner/divider means, or individual subarrays may be discretely connected to one or more waveguide sections in the rotating annulus. For power tapering across an antenna array aperture, the waveguide section dimensions in the circumferential direction within the rotating annulus are appropriately tailored.

摘要： An optical fiber having a conductive layer disposed therearound has sections removed therefrom that form gaps that expose the underlying optical fiber. Light manifolds are formed at each gap, such as are provided by Bragg gratings photoinduced in the core at each gap, and photoconductive material is disposed at each of the gaps. An opaque coating may optionally be disposed over the outside of the photoconductive material to ensure that it is activated by light propagating within the optical fiber. Light transmitted down the fiber may be controllably coupled output of the fiber at each of the gaps. The optical fiber thus provides multiple functions including electrical conductor, light manifold, and substrate on which the photoconductive material is deposited.
