    摘要: A compact multi-band ring-focus antenna system. The antenna system includes a first and a second main reflector 304, 306, each having a shaped surface of revolution about a common boresight axis (322) of the antenna. A first backfire type RF feed system (302, 312) is provided for feeding the first main reflector (304) on a first frequency band. A second RF feed (301) coaxial with the first RF feed (300) is provided for feeding the second main reflector (306) on a second frequency band spectrally offset from the first frequency band. Further a portion of the second RF feed passes through a first sub-reflector (302) of the backfire feed. The second RF feed is terminated a distance from the first sub-reflector to illuminate a second sub-reflector (303).

    摘要: A phased array antenna includes a substrate, and an array of dipole antenna elements on the substrate. Each dipole antenna element includes a medial feed portion, and a pair of legs extending outwardly therefrom. Pairs of adjacent legs of adjacent dipole antenna elements include respective spaced apart end portions. The phased array antenna further includes selectable impedance elements and switches. Each switch is for selectively coupling at least one impedance element between a respective pair of adjacent legs of adjacent dipole antenna elements for changing the capacitive coupling therebetween.

    摘要: An antenna feed system includes a plurality of RF horn antennas (201, 202) for operating on a plurality of RF frequency bands. A first one of the feed horns (202) can have a boresight axis and is configured for operating at a first one of the frequency bands. A second one of the feed horns (201) is positioned coaxially within the first one of the feed horns (202) and is configured for operating at least at a second one of the frequency bands. Further, the first one of the feed horns (202) is a corrugated horn that has a plurality of corrugations (204) formed on an interior surface defining a profile. The profile extends substantially from a throat (205) of the first feed horn and along a tapered portion of the first feed horn. The profile substantially minimizes an interaction of the corrugations with the second feed horn.

    摘要: The slot-mode antenna includes an array of slot antenna units carried by a substrate, and each slot antenna unit has a pair of patch antenna elements arranged in laterally spaced apart relation about at least one central feed position. Adjacent patch antenna elements of adjacent slot-mode antenna units include respective spaced apart edge portions defining gaps therebetween, and a capacitive coupling layer or plates overlap the respective spaced apart edge portions to provide increased capacitive coupling therebetween. The capacitive coupling layer may include continuous or periodic capacitive coupling plates along each gap defined by the respective spaced apart edge portions.

Each dipole antenna element includes a medial feed portion, and a pair of legs extending outwardly therefrom. Each dipole antenna element further includes a passive load, and a switch connected thereto for selectively coupling the passive load to the medial feed portion so that the dipole antenna element selectively functions as an absorber for absorbing received signals while the passive load dissipates energy associated therewith.
