    摘要： In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously. Furthermore, the antenna polarization may be static or dynamically controlled at the subarray or radiating element level.

    摘要： A steerable antenna or scanner assembly (10) is connected to signal process means (12). A housing (14) surrounds a focusing antenna (16) which is stationary relative to the housing (14), a polarisation rotator (18), a steerable reflector (20) angularly movable about a pivot axis (22), and a detector (24). Incoming radiation passes through the focusing antenna (16), has its polarisation altered as it passes through rotator (18), reflects off reflector (20), passes through rotator (18) again, encounters the antenna (16) again and this time reflects off it to focus down, passes through rotator (18) again, encounters the steerable reflector (20) again and this time passes through it to reach the detector (24). Moving the reflector (20) angularly steers the directional sensitivity of the assembly (10).

    摘要： A planar antenna according to the present invention includes a plurality of antenna elements arranged thereon and characterized in that two opposite corner parts from among corners of an N-gon (N is an even number equal to or greater than four) are cut out. For example, a planar antenna (1) has a shape in which two opposite corner parts (12 and 13) from among four corner parts included in a rectangle (11) (N=4) are cut out. The planar antenna (1) may be composed by combining a plurality of square antenna units (10) on which a plurality of antenna elements are arranged.

    摘要： A waveguide architecture for a dual-polarized antenna including multiple antenna elements. Aspects are directed to dual-polarized antenna architectures where each antenna element includes a polarizer having an individual waveguide with dual-polarization signal propagation and divided waveguides associated with each basis polarization. The waveguide architecture may include unit cells having corporate waveguide networks associated with each basis polarization connecting each divided waveguide of the polarizers of each antenna element in the unit cell with a respective common waveguide. The waveguide networks may have waveguide elements located within the unit-cell boundary with a small or minimized inter-element distance. Thus, unit cells may be positioned adjacent to each other in a waveguide device assembly for a dual-polarized antenna array without increased inter-element distance between antenna elements of adjacent unit cells. Antenna waveguide ports may be connected to unit cell common waveguides using elevation and azimuth waveguide networks of the corporate type.

    摘要： An antenna feed with mode suppression includes a transition section, having a window for connecting to an output port of a waveguide and having inner and outer conductors forming a coaxial waveguide that couples energy from the waveguide into a horizontal TE 11 mode in the coaxial waveguide. A polarizer section is coupled to the transition section and generates circular polarization from the horizontal mode of the transition section. A radiator section is coupled to the polarizer and provides an output signal for the antenna feed. The transition section includes an electrical short coupling the inner and outer conductors. The electrical short is disposed adjacent to the window of the transition section. A dielectric block is also disposed between the inner and outer conductors and adjacent to the electrical short along the axis of the coaxial waveguide. A surface of the dielectric block is coated with a thin film sheet resistance.

    摘要： A dual-band dichroic polarizer is provided for converting linearly polarized electromagnetic energy within distinct frequency bands into oppositely polarized circularly polarized electromagnetic energy. The polarizer includes an array of unit cells distributed across a sheet, wherein the unit cells each include a stack of one or more resonant structures, the stack configured to introduce a phase differential of approximately +90° to linearly polarized electromagnetic energy within a first distinct frequency band that is incident upon and passes through the sheet, and configured to introduce a phase differential of approximately -90° to linearly polarized electromagnetic energy within a second distinct frequency band, separate from the first distinct frequency band, that is incident upon and passes through the sheet, a linear polarization of the electromagnetic energy in the first distinct frequency band and a linear polarization of the electromagnetic energy in the second distinct frequency band being the same.
