摘要： A ring focus antenna and method of using same. The ring focus antenna can have a main reflector of revolution shaped as a non-regular paraboloid about a boresight axis of the antenna. A sub-reflector/feed pair is provided comprising a sub-reflector of revolution shaped as a non-regular ellipsoid having a ring-shaped focal point about the boresight axis. A feed element is installed at a feed element location separated spaced from a vertex of the sub-reflector on the boresight axis of the antenna. The main reflector is adapted for operation with multiple sub-reflector/feed pairs having a coupled configuration, and multiple sub-reflector/feed pairs having a decoupled configuration (i.e. classical optical dual reflector system). The main reflector is operable at a plurality of spectrally offset frequency bands. For example, the antenna can be designed for operation over C-band, X-band, Ku-band, and Ka-band.

摘要： A multiband, shaped ring focus antenna architecture employs only a single or common main reflector, that is shaped such that it can be shared by each of a pair of interchangeable, diversely shaped close proximity-coupled, subreflector-feed pairs designed for operation at respectively different spectral bands. The operational band of the antenna is changed by swapping out the subreflector-feed pairs. Placement of the shaped subreflector in close proximity to the feed horn reduces the diameter of the main shaped reflector relative to a conventional ring focus structure, so as to facilitate installation within a constrained space facility, such as a shipboard-mounted satellite communication system.

摘要： An antenna system comprising a feed array, a subreflector and a main reflector which are oriented to define a folded optics antenna geometry. The feed array is comprised of a plurality of separate feeds which are aligned on a predetermined contour. Each feed is coupled to a feed network which acts to combine the illumination beams of a preselected number of feeds to produce a plurality of composite illumination beams. Each composite illumination beam is directed to be incident upon a separate predetermined location on the subreflector which directs the illumination beams towards the main reflector. Each composite illumination beam is reflected by the main reflector in a preselected direction so that each composite illumination beam forms an antenna beam that impinges a predetermined coverage area on the Earth. Each antenna beam defines a separate coverage cell in the coverage area, wherein the position and orientation of the feeds, the subreflector and the main reflector provides adjacent, antenna beams over a full Earth field of view coverage area where each antenna beam is approximately symmetrically shaped.

Each composite illumination beam is directed to be incident upon a separate preselected location on the subreflector which directs the composite illumination beams towards the main reflector. Each composite illumination beam is reflected by the main reflector in a preselected direction so that each composite illumination beam forms an antenna beam that impinges a predetermined coverage area on the Earth.

摘要： The invention concerns an antenna with high scanning capacity. The antenna comprises a panel (30) of static radiating elements which are controlled to transmit in variable directions relative to a direction (38) perpendicular to the plane of the panel. Reflectors (34, 44) amplify the scanning effected by the panel (30) of radiating elements. The reflectors (34, 44) are segments of paraboloids with the same axis (38) and the same focus (40), for example.

摘要： A splashplate antenna system configured using hybrid mode-matching techniques has improved secondary beam characteristics, including improved sidelobe performance, improved electric and magnetic plane correlation, reduced cross-polarization, improved electric and magnetic plane phase center correlation, and improved overall matching between the waveguide and the splashplate (sub-reflector). Internally, the waveguide contains a wall constructed from a series of varying dimensioned cross-sections that cause signals introduced to radiate in a multiple mode, Gaussian-like field pattern. The Splashplate is configured so that the waves received from the waveguide maintain the circular pattern symmetry, as well as other characteristics.

摘要： A dual-reflector microwave antenna includes a main reflector having a shape that is a portion of a paraboloid generated by revolution of a parabola around having a single, common axis of rotation and symmetry. A primary feed extends along the axis of the main reflector on the concave side of the main reflector, and a subreflector located beyond the end of said primary feed has an image-inverting surface configuration that has a ring focus located between the main reflector and the subreflector and extending around the axis of the main reflector. In either a single or dual-reflector antenna, the main reflector has a shield with a band of dielectric or conductive material extending around at least a portion of the inner surface of the shield for reducing the return loss of the antenna. Patterns may be improved by providing a shield of absorber material extending around the outer periphery of at least an end portion of the primary feed. In the case of a dual-reflector antenna, return loss may be reduced by providing a dielectric or electrically conductive element between the primary feed and the subreflector, and/or by providing an annulus of absorber material on the surface of the subreflector.
