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.

摘要： The present invention is directed generally to phased array antennas. The invention allows for the realization of a low-cost, ferroelectric material loaded feed manifold for phase shifting an antenna. This type of architecture can take many forms, with the preferred embodiment being waveguide. In an embodiment of the present invention, the Ferroelectric/Paralectric/Composite material loaded feed manifold described herein may solve the space/weight problem by integrating the material into the traditional waveguide feed manifold. A feed structure suitable for receiving and routing electromagnetic energy may include a subassembly including material suitable for shifting phase of electromagnetic radiation when an electrical field is applied. Material having a dielectric constant at least one of equal to and greater than the phase shifting material may also be included.

摘要： A combined pulsed and FMCW AESA radar system is described. The radar system includes an AESA array of radiating elements, an array of TR modules, an RF combiner/splitter, a transmitter, a pulsed radar receiver and an FMCW radar receiver. Each TR module corresponds to a respective radiating element of the array of radiating elements. The transmitter is configured to transmit an excitation signal to excite selected or all radiating elements of the array of radiating elements via the TR modules. When the transmitter is in a pulsed radar mode, the pulsed radar receiver is configured to receive radar return signals via the RF combiner/splitter from radiating elements of the array of radiating elements via the TR modules. When the transmitter is in an FMCW radar mode, the FMCW radar receiver is configured to receive radar return signals from selected radiating elements of the array of radiating elements via the TR modules.

摘要： The present disclosure includes a method for producing a multi-band waveguide reflector antenna feed. The antenna feed includes a first tube and a second tube. 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.
