    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: The dual-polarization, slot-mode antenna includes an array of dual-polarization, slot-mode, antenna units carried by a substrate, with each dual-polarization, slot-mode antenna unit having at least four patch antenna elements arranged in spaced apart relation about a central feed position. Adjacent patch antenna elements of adjacent dual-polarization, slot-mode antenna units include respective spaced apart edge portions having predetermined shapes and relative positioning to provide increased capacitive coupling therebetween. The respective spaced apart edge portions may be continuously or periodically interdigitated to provide the increased 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: An antenna assembly includes at least two active or main radiating omni-directional antenna elements arranged with at least one beam control or passive antenna element used as a reflector. The beam control antenna element(s) may have multiple reactance elements that can electrically terminate it to adjust the input or output beam pattern(s) produced by the combination of the active antenna elements and the beam control antenna element(s). More specifically, the beam control antenna element(s) may be coupled to different terminating reactances to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use. Consequently, the radiator pattern of the antenna can be more easily directed towards a specific target receiver/transmitter, reduce signal-to-noise interference levels, and/or increase gain. A Multiple-Input, Multiple-Output (MIMO) processing technique may be employed to operate the antenna assembly with simultaneous beam patterns.
