  • Publication number: 20230395971
    Abstract: A base station antenna comprises a reflector assembly and a first radiating element having a first feed stalk and a first radiator. A base of the first feed stalk is adjacent the reflector assembly and the first radiator is adjacent a distal end of the first feed stalk. A center of the first radiator is offset from the base of the first feed stalk in a longitudinal direction that is parallel to a longitudinal axis of the base station antenna.

  • Patent number: 11081789
    Abstract: Base station antennas are provided herein. A base station antenna includes first and second wiper phase shifters. In some embodiments, the base station antenna includes first and second wiper supports that are on the first and second wiper phase shifters, respectively, and the first wiper support includes a portion that is beside and interlocked with a portion of the second wiper support. In some embodiments, the base station antenna includes a first linkage that is on the second wiper phase shifter, and a second linkage that intersects, and is coupled to, the first linkage and is configured to adjust the first and second wiper phase shifters via the first linkage. In some embodiments, the first and second wiper phase shifters are a mirror-image pair of wiper phase shifters. Related methods of operating a base station antenna are also provided.

  • Patent number: 10833461
    Abstract: A connector for connecting a coaxial cable to a printed circuit board includes a support portion that receives an end of the coaxial cable within a hollow structure thereof so that an exposed outer conductor of the coaxial cable is connected to an interior surface of a side wall of the hollow structure and so that the coaxial cable extends within the support portion perpendicular to the printed circuit board. The connector further includes an engagement portion that is connected to the support portion and configured to fix the connector to a first side of the printed circuit board, where the engagement portion is mounted above a via hole in the printed circuit board.
