摘要： A phased array antenna is made up of linear arrays. Each of the linear arrays has a printed circuit board spine. Split waveguides are formed from two symmetrical portions conductively joined to ground on opposite sides of the printed circuit board spine. Planar transmission line-to-waveguide transitions are mounted on the printed circuit board spine within the split waveguides. Phase shifter/TTD devices are mounted on the circuit board spine within the split waveguides for steering the phased array antenna beam. Bias and control circuitry is etched on the circuit board spine for biasing and controlling the phase shifter/TTD devices. The phased array antenna may be made up of the linear arrays combined into a two-dimensional array and fed with a waveguide feed or a printed feed manifold attached to the printed wiring board spine.

摘要： An electronically scanned slotted waveguide antenna radiates an RF signal as a scannable beam. The antenna has radiation waveguides positioned in an array. Radiation slots in the radiation waveguides radiate the scannable beam. A feed waveguide is coupled to the radiation waveguides. The feed waveguide feeds the RF signal to the radiation waveguides through coupling slots. The feed waveguide has sidewalls with tunable electromagnetic crystal (EMXT) structures thereon. The EMXT structures vary the phase of the RF signal in the feed waveguide to scan the radiated beam in one dimension. The radiation waveguides may also have tunable EMXT structures on the sidewalls to vary the phase of the RF signal to scan the radiated beam in a second dimension. The EMXT structures may be discrete EMXT devices or a EMXT material layer covering the feed and radiation waveguide sidewalls.

The first and second tubes are connected to form a concentric multi-band waveguide feed array. The first tube includes a surface(s) which is/are at least partially covered by metamaterial(s), thereby forming a first waveguide feed. The second tube also includes a surface(s) which is/are at least partially covered by metamaterial(s). A radial separation is established between the first tube and the second tube, thereby forming a second waveguide feed. The radial separation may be maintained between the first tube and the second tube by one or more of: a loading material, support structures, strings, and wires. The loading material, support columns, strings, and/or wires also structurally interconnect the first tube and the second tube.

摘要： A phased array antenna with an egg crate array structure is formed from metallic row slats that form a floor and ceiling of each array element. Column slats with slots engage the row slots to form the egg crate array structure. EMXT devices are located on the column slats such that a pair of EMXT devices form array element walls. The column slats are formed from U-shaped column strips configured such that a left side of the U-shape forms a left-hand side of each array element in a column and a right side of the U forms an opposing right-hand side. The column strips sides are mounted back-to-back with sides of adjacent column strips to form the column slats. Circuit devices for operation of the antenna are mounted on the U-shaped column strip and a connector is mounted at an apex of the U-shaped column slat.

摘要： A dual-band stacked electromagnetic band gap (EBG) electronically scanned array (ESA) has a high-frequency aperture stacked on a low-frequency aperture. The high-frequency aperture looks through the low-frequency aperture. Low-frequency and high-frequency feeds feed the apertures. The low-frequency aperture comprises low-frequency cells with two vertical low-frequency EBG sidewalls and two horizontal metal walls. The high-frequency aperture comprises high-frequency cells with four cells stacked on each of the low-frequency cells. The four high-frequency cells comprise four vertical high-frequency EBG sidewalls, two horizontal metal top and bottom metal walls, and a center horizontal metal wall for operation with the same polarization as the low-frequency aperture. The high-frequency cells may comprise four horizontal high-frequency EBG sidewalls, two vertical left and right metal walls, and a center vertical metal wall for orthogonal polarization. A frequency selective surface may be used to provide isolation between the apertures.

摘要： A wafer-scale heterogeneous layered active electronically scanned array (ESA) utilizes a low-loss integrated waveguide feed. The ESA is formed from wafer-scale subarray modules each of which comprises a multilayer stack to form transmit/receive (T/R) modules. Waveguide subarray combiners feed the T/R modules. A subarray combiner is a waveguide assembly bonded to a bottom layer in the multilayer stack. The bottom layer is a ground plane forming a top waveguide broadwall of the combiner. The waveguide subarray combiner may be formed from a variety of waveguide types and feeds the T/R modules using electric field probe coupling or an aperture slot coupling. A second layer feed structure forms the subarray modules into the ESA and feeds the waveguide subarray combiners. The second layer feed structure uses waveguides to feed the waveguide subarray combiners using E-field probes or aperture slot coupling on the bottom waveguide broadwall.

摘要： A method of forming a conformal electronic scanning array (ESA) is disclosed. The ESA is formed using rolling techniques similar to those used in forming LCD displays. If the layers forming the ESA are made of substantially transparent materials, the ESA may be applied to an outer surface of a display, such as a flexible display. The ESA may also be applied to a window or other non-planar surface such as an outer surface of a vehicle, or may be integrated into a computer display.
