    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 tubular slot-mode antenna includes an array of slot antenna units carried by a tubular substrate, e.g. a cylindrical substrate, and each slot antenna unit having 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 have respective spaced apart edge portions with predetermined shapes and relative positioning to provide increased capacitive coupling therebetween. The array of slot-mode antenna units may define a plurality of ring-shaped slots coaxial with an axis of the tubular substrate, and a feed arrangement may be coupled thereto to operate the array of slot-mode antenna units in an endfire mode.

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).
