  • Publication number: 20060273865
    Abstract: An antenna comprising a reflective surface; and an array of dipole antenna elements disposed adjacent to the reflective surface. Each antenna element has a pair of arms which together define a dipole axis, and the dipole axis is tilted at an acute angle with respect to the reflective surface. The pair of arms may be dipole arms, or may be Yagi director arms. In some embodiments the dipole axis is tilted at an acute angle with respect to a feed axis. In some embodiments the antenna element comprises a feed portion defining a feed axis; and the feed portion has a mounting portion which is tilted at an acute angle with respect to the feed axis.

  • Publication number: 20050253769
    Abstract: A crossed dipole antenna element comprising first and second dipoles, each dipole having a pair of arms, each arm having a first portion extending from a central axis and a second portion extending out of a plane including the first portion and the central axis. In certain embodiments the second portions of the arms of the first dipole extend in a first rotational direction and the second portions of the arms of the second dipole extend in a second rotational direction. This improves the isolation performance of the antenna. In certain embodiments the second portion of each arm branches out at an intermediate position along the length of the arm. This improves the bandwidth performance of the antenna.
