  • Omnidirectional multiple input multiple output (MIMO) antennas with polarization diversity
    Patent number: 8368609
    Abstract: Exemplary embodiments are provided of omnidirectional MIMO antennas with polarization diversity. In one exemplary embodiment, an omnidirectional MIMO antenna generally includes an array of radiating antenna elements having a linear horizontal polarization and radiating omnidirectionally in azimuth. The antenna also includes at least one radiating antenna element having a linear vertical polarization and radiating omnidirectionally in azimuth. The vertically polarized radiating antenna is spaced-apart from the array. The antenna is operable for producing omnidirectional, vertically polarized coverage for at least one port, as well as omnidirectional, horizontally polarized coverage for at least one other port.

  • System and method for securing an antenna
    Patent number: 7161554
    Abstract: A bracket for securing an antenna to a ceiling grid system has a first opening to allow the bracket to be secured to a connector mechanically coupled to the ceiling grid system and a second opening to allow an electrical connection to pass therethrough. The second opening is offset a distance from the first opening to allow the electrical connection to extend upwardly without being obstructed by the ceiling grid.
