  • Publication number: 20180331419
    Abstract: A base station antenna includes a panel that has a ground plane, first and second arrays that have respective first and second sets of linearly arranged radiating elements mounted on the panel, and a decoupling unit positioned between a first radiating element of the first array and a first radiating element of the second array. The decoupling unit includes at least a first sidewall that faces the first radiating element of the first array, a second sidewall that faces the first radiating element of the second array and an internal cavity that is defined in the region between the sidewalls. The first and second sidewalls are electrically conductive and electrically connected to the ground plane.

  • Publication number: 20180323513
    Abstract: A dual-polarized radiating element for a base station antenna includes a first dipole that extends along a first axis, the first dipole including a first dipole arm and a second dipole arm and a second dipole that extends along a second axis, the second dipole including a third dipole arm and a fourth dipole arm and the second axis being generally perpendicular to the first axis, where each of the first through fourth dipole arms has first and second spaced-apart conductive segments that together form a generally oval shape.

  • Publication number: 20180201785
    Abstract: The invention generally relates to compositions comprising polymer bottle brush and comb networks and methods of making polymer networks. Specifically, the disclosed polymer networks are prepared by polymerizing a siloxane monomer in the presence of a crosslinker. Alternatively, the disclosed polymer networks can be prepared by polymerizing a siloxane monomer in the presence of a radical initiator. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

  • Patent number: 6420965
    Abstract: In a method of controlling a vibrator, the vibrator is first driven towards a first frequency during a first interval and then is driven towards a second frequency during a second interval. In a preferred embodiment the first frequency is higher than the lowest resonance frequency of the vibrator and the vibrator is then allowed to reduce the frequency to a frequency lower than the resonance frequency. By letting the frequency vary in a pulsating manner in the vibrating device, the vibration can be sensed more easily by a human, and thereby making it possible to use a very small mass in the vibrating device, which therefore can be made using a small weight, while still making it possible to sense the vibration.
